Scan Start Condition Two or more non-prio

11、rity channels must be added to all channels that can be scanned. The transceiver must be in normal receive mode (PTT off). When you activate the key or the toggle switch (to right position) programmed to the scan function, the scan starts. The scan icon SCN lights and SCAN or revert channel (program

12、mable) is indicated on 7-digit alphanumeric display. 2-2. Scan Stop Condition The scan stops temporarily if the following conditions are satisfied. 1) A carrier is detected, then signalling matches on channel for which receive the signalling is set by the program- ming software. 2) A carrier is dete

13、cted on the channel for which receiving signalling is not set by the programming software or when the monitor (signalling cancel) function is activated. 2-3. Scan Channel Types 1) Priority channel is the most important channel for the scan, and always detects a signal during scan and when the scan s

14、tops temporarily. 2) Non-priority channels detects a signal during scan. For the channels that can be selected with the channel selec- tor when the scan does not occur, adds an indicator A lights. 2-4. Priority Channel Setting Priority channel can be set as follows with the program- ming software (K

15、PG-59D). 1) Specify priority channel as fixed priority channel. 2) Make selected channels, priority channels. 2-5. Scan Type According to the Priority Channel 1) When no priority channels are set : Only the non-priority channels are scanned. If a non-priority channel stops temporarily. 2) When one p

16、riority channel is set : Either priority channel is scanned. If a non-priority channel stops temporarily, a priority chan- nel signal is detected at certain intervals. If a priority channel stops temporarily, it stops until there is no signal on the priority channel. 2-6. Revert Channel The revert c

17、hannel is used to transmit during scanning and set by the programming software (KPG-59D). 1) Last called channel The transceiver reverts to the last called channel during the scan. 2) Last used channel The transceiver reverts to the last used (transmitted) channel during scan. Last used revert chann

18、el includes talkback function. 3) Selected with talkback The transceiver reverts to the channel before scanning or the channel that you changed during scan. 4) Selected channel The transceiver reverts to the channel before scanning or the channel that you changed during scan. 5) Priority with talkba

19、ck The transceiver reverts to the priority channel. If you press PTT during a resume timer (dropout delay time, TX dwell time) or calling, you can transmit on cur- rent channel to answer to the call however revert channel is set to priority channel. After resume time, scan re-starts and transmission

20、 chan- nel is return to priority channel. 6) Priority The transceiver reverts to the priority channel. 2-7. Scan End When you press the key once again, or the toggle switch (to left position) programmed to the scan function during scan mode, the scan ends. The scan icon SCN and SCAN or revert channe

21、l (pro- grammable) display goes off. 2-8. Temporarily Delete/Add It is possible to delete or add channel temporarily during scan. When scan stops on unnecessary channel for ex- ample by interference of the other party, activate the delete/ add function (for example press the key), then that channel

22、is deleted temporarily and scan re-start immediately. When you would like to add the deleted channel tempo- rarily to scan sequence, select the desired (deleted) channel during scan, activate the delete/add function (for example press the key) before scan re-start. That channel is added temporarily

23、to scan sequence. The temporary deleted or added channels are returns to pre-set delete/add, when the transceiver exits from scan mode. 5 TK-190 OPERATING FEATURES 3-10. Emergency Channel Display The transceiver can be programmed to display EMER- GENCY channel name when it is in emergency mode. If y

24、ou set to off by KPG-59D the transceiver shows se- lected group/channel/status before entering to the emer- gency mode however the transceiver is in an emergency mode. 3-11. Clear to Transpond The transceiver waits the transpond of 2-Tone/DTMF if channel is busy until channel open. This feature prev

25、ents the interference to other party. 3-12. External Speaker It can be selected if the receive sound is made by SP-Mic SP or the main body SP at a SP-Mic mount. 3-13. Mode (Enable/Disable) The transceiver has many special modes mainly for main- tenance. Panel Test mode Clone mode Main programming mo

26、de It is possible to set enable/disable for each mode. We recommend to set these mode to Disable after set up to save contents. 3-14. ID The transceiver is capable to have ID. The format is DTMF. The timing that the transceiver sends ID is program- mable. Begin of TX : Connect ID is send on beginnin

27、g of trans- mission. End of TX : Disconnect ID is send on end of transmission. Both : Connect ID is send on beginning of transmission and disconnect ID is send on end of transmission. Off : Sending ID function is disabled. There is also PTT ID setting for each channel. Refer PTT ID of channel featur

28、e. 3-15. OST (Operator Selectable Tone) The transceiver is capable to have OST function and 16 tone pair (QT/DQT) with max 7-digit name for each tone pair. OST Back Up The transceiver is programmable the selected OST code is memorized or not. If you set to Disable (no memo- rized), the OST function

29、always starts at off. 3-16. Data Password (Keypad Model Only) The data password prevents unauthorized reading of the programmed transceiver data by FPU. Enter pre-pro- grammed password in FPU reading process. 3.Optional Features You can use these features using the programming soft- ware (KPG-59D).

30、3-1. Beep Tones The beep tones (power on tone, control tone, warning tone, alert tone) are individually programmable to the fixed level 0 to 31 or follow the mechanical volume position. 3-2. Minimum Volume The minimum volume is programmable (0 to 31). The transceiver remains the minimum volume level

31、 however the mechanical volume position is set to zero. 3-3. BCL (Busy Channel Lockout) Override You can transmit in spite of Busy Channel Lockout situa- tion. For example : To make an emergency voice call. To transmit under busy channel lockout situation, press PTT once more within approx. 500ms af

32、ter the PTT release. 3-4. Selective Call Alert LED You can select whether or not the LED on the transceiver flashes in an orange color when Selective call was occurred. 3-5. Battery Warning This transceiver has battery warning feature. If the low voltage is detected during transmission, the transcei

33、ver warns it by flashing red LED. Then more low voltage is detected during transmission, the transceiver stops transmission and warns it by flashing red LED and beep. Please notice standard for the battery exchange, charg- ing time by flashing red LED and beep. 3-6. Busy LED You can program the enab

34、le or disable the busy LED function when a carrier is detected. Disable saves battery life. 3-7. TX LED You can program the enable or disable the transmission LED function. 3-8. 2-Digit 7-Segment Display You can use 2-digit 7-segment the display to display the channel number or group number. It is u

35、seful when the main (7-digit 13-segment) display indicates channel name. 3-9. Invert Display Main (7-digit 13-segment) display and sub (2-digit 7-seg- ment) display can be programmed to invert display. It is easy to read the display when the operator sus- pended the transceiver on a waste belt. The

36、operator also can change the display between normal and invert using key. Refer the invert display function of key function. 6 TK-190 OPERATING FEATURES 3-17. TOT (Time-Out Timer) The transceiver has the TOT. This parameter selects the period of time users can continuously transmit. When the selecte

37、d period passes, the transceiver gener- ates an warning tone and stops the transmission. 3-18. TOT Pre-Alert The transceiver has TOT pre-alert timer. This parameter selects the time at which the transceiver generates TOT pre-alert tone before TOT is expired. TOT will be expired when the selected tim

38、e passes from a TOT pre-alert tone. 3-19. TOT Re-Key Time The transceiver has TOT re-key timer. This timer is the time you can not transmit after TOT exceeded. After TOT re-key time expired you can transmit again. 3-20. TOT Reset Time The transceiver has TOT reset timer. This timer is the minimum wa

39、it time allowed during a transmission that will reset the TOT count. TOT reset time causes the TOT to continue even after PTT is released unless the TOT reset timer has expired. 3-21. Signalling Signalling AND/OR sets the audio unmute condition for any channel programmed with the option signalling (

40、2-Tone/ DTMF). AND : AND requires both the valid option signalling and the programmed QT/DQT to be received for audio to unmute (and initiate an option signalling decode alert). OR : OR requires either the valid option signalling or the programmed QT/DQT to be received for audio to unmute (an option

41、 signalling decode alert is only initiated if the proper option signalling is decoded). 3-22. Noise Canceling Microphone Reduce the background noise. 4.Channel Features You can use these features using the programming soft- ware (KPG-59D). 4-1. Alphanumeric Display (Channel Name) The programming sof

42、tware (KPG-59D) enables you to set the alphanumeric display for channel name. The total text size of channel name are 7-digits. For example, If you set 2-digits for group name, then you can use 5-digits for channel name. The characters can be used as shown in Figure 1. Fig. 1 ABCDEFG HI JKL M N OPQR

43、 STUV W XYZ 123456789 0- All on 4-2. Option Signalling The transceiver is programmable to the option signalling (2-Tone decode program 1, 2-Tone decode program 2, 2- Tone decode program 3, DTMF decode) to each channel. It is useful to receive an individual call. Receive format is selectable AND or O

44、R with QT/DQT. The radio response of option signalling is programmable call Alert and Transpond for each option signalling (2-Tone de- code program 1, 2-Tone decode program 2, 2-Tone decode program 3, DTMF). 4-3. PTT ID PTT ID provides a DTMF ANI to be sent with every time PTT (connect ID at beginni

45、ng of transmission, disconnect ID at end of transmission, or both). You can program PTT ID on or off for each channel. The contents of ID are programmed for each transceiver. 4-4. Busy Channel Lockout Transmission is inhibited when the channel is busy. It is able to set this feature Yes or No for ea

46、ch channel. 4-5. Beat Shift This is the feature that the microprocessor shifts its sys- tem clock frequency slightly to prevent the receive interfer- ence. This transceiver can program this feature Yes or No for each channel. 7 TK-190 OPERATING FEATURES 4-6. TX Power You can set the transmission power High or Low for each channel. The each power setting is tuned at factory. However, you can re-tune the power, using PC Tuning Mode of
