1、1 VX-1210 Service Manual Introduction This manual provides technical information necessary for servicing the VX-1210 Transceiver. Servicing this equipment requires expertise in handling surface-mount chip components. Attempts by non-qualified persons to service this equipment may result in permanent

2、 damage not covered by the warranty, and may be illegal in some countries. Two PCB layout diagrams are provided for each double-sided circuit board in the transceiver. Each side of thr board is referred to by the type of the majority of components installed on that side (“leaded” or “chip-only”). In

3、 most cases one side has only chip components, and the other has either a mixture of both chip and leaded components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only. While we believe the technical information in this manual to be correct, VERTEX STANDARD assumes no l

4、iability for damage that may occur as a result of typographical or other errors that may be present. Your cooperation in pointing out any inconsistencies in the technical information would be appreciated.

Wh

32、en the “TELCALL” feature is activated, the clarifier is dis- abled. Sending a TELCALL 1. Press the TOGGLE switch (assigned to the “SELCALL” fea- ture) momentarily to enable selection of the code memory. 2. Rotate the SEL knob to select (display) the code memory of the station you want to SELCALL. 3.

33、 Press the TOGGLE switch (assigned to the “TELCALL” fea- ture) momentarily to enable to TELCALL feature. 4. Rotate the SEL knob to select the Autopatch memory string you wish to send. 5. Press and hold in the TOGGLE switch (assigned to the “TELCALL” feature) for 1/2 second to send the TELCALL (corre

34、sponding to a telephone number). 6. When the communication is finished, press and hold in the TOGGLE switch (assigned to the “TELCALL” feature) for 1/2 second, while holding in the PTT switch to send the “Hang-up” signal. Manual Sending If your VX-1210 has not had the telephone number stored into th

35、e Autopatch memory, you can pre-program and send the tele- phone number temporarily. Here is the manual sending procedure: 1. Call the station that is connected to the telephone system via the SELCALL feature first, as described previously. 2. Press the TOGGLE switch (assigned to the “TELCALL” fea-

36、ture) momentarily. 3. Rotate the SEL knob to select (display) “AUX xxxx.” 4. Press and hold in the SEL knob for 1/2 second, then rotate the SEL knob to select the first digit of the telephone number you want to send. 5. Press the SEL knob momentarily to step to the next digits place. Use the SEL kno

37、b again to select a number and to step to the next entry. 6. After entering all digits of the telephone number you want to send, press and hold in the SEL knob for 1/2 second to save the telephone number into the Autopatch memory temporarily. 7. Press and hold in the TOGGLE switch (assigned to the “

38、TELCALL” feature) for 1/2 second to send a TELCALL (corresponding to the telephone number). SELCALL Operation The VX-1210 SELCALL feature allow paging and selective call- ing using 4-digit codes transmitted as an FSK format. Your re- ceiver remains silent until it receives 4-digit codes that match t

39、hose stored in a dedicated code memory. When the SELCALL feature is activated, the clarifier is disabled. Receiving a SELCALL When a SELCALL is decoded, an alert ringer sounds for 30 sec- onds, and appear the ID code of the calling stations (such as “ID1234”) will appear in the display. If a private

40、 SELCALL is detected, the VX-1210 send the answer back signal to the call- ing station automatically before the alert ringer sounds. Unless you respond, the alert beeper will be heard every three seconds, and the “CALL RECEIVED plus the calling stations ID Code” will appear in the display until you

41、do respond. Sending a SELCALL 1. Press the TOGGLE switch (assigned to the “SELCALL” feature) momentarily to enable selection of the code memory. 2. Rotate the SEL knob to select (display) the code memory of the station you want to SELCALL. 3. Press and hold in the TOGGLE switch (assigned to the “SEL

42、CALL” feature) for 1/2 second to send the SELCALL. Manual Sending If your VX-1210 has not been programmed with the 4-digit codes for the “SELCALL” feature into the code memory, you can pre- program and send the 4-digit code manually as a temporary mea- sure. Here is the SELCALL manual sending proced

43、ure: 1. Press the TOGGLE switch (assigned to the “SELCALL” feature) momentarily. 2. Rotate the SEL knob to select (display) “AUX xxxx.” 3. Press and hold in the SEL knob for 1/2 second, then rotate the SEL knob to select the first number of the 4-digit code you want to send. 4. Press the SEL knob mo

44、mentarily to step to the next digits place. Use the SEL knob again to select a number and to step to the next entry. 5. After entering all four numbers you want to send, press and hold in the SEL knob for 1/2 second to save the 4 digits into the code memory temporarily. 6. Press and hold in the TOGG

45、LE switch (assigned to the “SELCALL” feature) for 1/2 second to send the SELCALL.

46、realignment should not be done until after the faulty component has been replaced. We recommend that servicing be performed only by autho- rized Vertex Standard service technicians who are experienced with the circuitry and fully equipped for repair and alignment. Therefore, if a fault is suspected,

47、 contact the dealer from whom the repeater was purchased for instructions regarding repair. Au- thorized Vertex Standard service technicians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty components. Those who do

48、undertake any of the following alignments are cautioned to proceed at their own risk. Problems caused by un- authorized attempts at realignment are not covered by the war- ranty policy. Also, Vertex Standard reserves the right to change circuits and alignment procedures in the interest of improved p

49、erformance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function and operation of the transceiver are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and realignment determined to be absolutely ne
