If CTCSS or Digital Coded Squelch (DCS) Lock-

out has been programmed on a channel, the radio can transmit only when there is no carrier being received or when the carrier being received in-

cludes the correct CTCSS tone or DCS code. Automatic Time-Out Timer If the selected channel has been programmed for automatic time-out, you must limit the length of each transmission. While transmitting, a beep will sound 10 seconds before time-out. Another beep will sound just before the deadline; the TX indicator will dis-

appear and transmission will cease soon thereafter. To resume transmitting, you must release the PTT switch and wait for the penalty timer to expire.

If a Speaker/Microphone is available, remove the plastic cap and its two mounting screws from the right side of the transceiver, then align the con-

nector of the Speaker/Microphone on the trans-

ceiver body; secure the connector pin using the screws supplied with the Speaker/Microphone. Hold the speaker grille up next to your ear while receiving. To transmit, press the PTT switch on the Speaker/Microphone, just as you would on the main transceivers body, and speak into the microphone on a normal voice level. Note 1): Save the original plastic cap and its mounting screws. They should be reinstalled when not using the Speaker/Microphone. 2) When you press the PTT switch on the Speaker/Microphone, it disables the internal mi-

crophone, and vice versa.

If the Busy Channel Lockout feature has been programmed on a channel, the radio will not trans-

mit when a carrier is present. Instead, the radio will generate short beep three times and indicate

* ERROR * on the display. Release the PTT switch and wait for the channel to be clear of ac-

tivity. VX-P920/-P970 OPERATING MANUAL 9 ADVANCED OPERATION Programmable Key and Toggle Switch Functions The VX-P920/-P970 includes the TOP SEL, SIDE SEL, MONITOR, and LAMP keys, the TOGGLE switch, and [A], [B], [C], [D], [], [#] function keys. The Programmable key and TOGGLE switch func-

grammed (by your dealer) to that switch position will be activated. See the next section for details regarding the available features. 7 OPERATION

If CTCSS or Digital Coded Squelch (DCS) Lock-

out has been programmed on a channel, the radio can transmit only when there is no carrier being received or when the carrier being received in-

cludes the correct CTCSS tone or DCS code. Automatic Time-Out Timer If the selected channel has been programmed for automatic time-out, you must limit the length of each transmission. While transmitting, a beep will sound 10 seconds before time-out. Another beep will sound just before the deadline; the TX indicator will dis-

appear and transmission will cease soon thereafter. To resume transmitting, you must release the PTT switch and wait for the penalty timer to expire.

If a Speaker/Microphone is available, remove the plastic cap and its two mounting screws from the right side of the transceiver, then align the con-

nector of the Speaker/Microphone on the trans-

ceiver body; secure the connector pin using the screws supplied with the Speaker/Microphone. Hold the speaker grille up next to your ear while receiving. To transmit, press the PTT switch on the Speaker/Microphone, just as you would on the main transceivers body, and speak into the microphone on a normal voice level. Note 1): Save the original plastic cap and its mounting screws. They should be reinstalled when not using the Speaker/Microphone. 2) When you press the PTT switch on the Speaker/Microphone, it disables the internal mi-

crophone, and vice versa.

If the Busy Channel Lockout feature has been programmed on a channel, the radio will not trans-

mit when a carrier is present. Instead, the radio will generate short beep three times. Release the PTT switch and wait for the channel to be clear of activity. 8 VX-P920/-P970 OPERATING MANUAL NOTE VX-P920/-P970 OPERATING MANUAL 9 ADVANCED OPERATION Programmable Key and Toggle Switch Functions The VX-P920/-P970 includes the TOP SEL, MONITOR, SIDE SEL 1, and SIDE SEL 2 keys, and the TOGGLE switch.

(unmute the audio); the BUSY/TX indicator will glow green. SCAN The Scanning feature is used to monitor multiple sig-

nals programmed into the transceiver. While scan-

ning, the transceiver will check each channel for the presence of a signal, and will stop on a channel if a signal is present. To activate scanning:

Press the assigned programmable key to activate scanning.

The scanner will search the channels of each chan-

nel, looking for active ones; it will pause each time it finds a channel on which someone is speak-

ing.

Press the assigned programmable key again to disable scanning. Operation will revert to the pro-

grammed revert channel. VX-P920/-P970 OPERATING MANUAL Note: Your dealer may have programmed your ra-

dio to stay on one of the following channels if you press the PTT switch during scanning pause:

 Current channel (Talk Back)

ture, except that only two channels are monitored:

 The current operating channel; and

 The Priority channel. To activate Dual Watch:

Press the assigned programmable key.

The scanner will search the two channels; it will pause each time it finds a channel on which some-

one is speaking. To stop Dual Watch:

Press the assigned programmable key.

Operation will revert to the Dual Watch Start channel. 11 ADVANCED OPERATION TX SAVE DISABLE Press the assigned programmable key to disable the Transmit Battery Saver, if you are operating in a lo-

cation where high power is almost always needed. The Transmit Battery Saver helps extend battery life by reducing transmit power when a very strong sig-

nal from an apparently nearby station is being re-

ceived. Under some circumstances, though, your hand-held radio may not be heard well at the other end of the communication path, and high power may be necessary at all times. LOW POWER Press the assigned programmable key to set the radios transmitter to the Low Power mode, thus extending battery life. Press the key again to return to Normal transmit power when in difficult ter-

rain. TALK AROUND (TA) Press the assigned programmable key to activate the Talk Around feature when you are operating on du-

plex channel systems (separate receive and transmit frequencies, utilizing a repeater station). The Talk Around feature allows you to bypass the repeater sta-

tion and talk directly to a station that is nearby. This feature has no effect when you are operating on sim-

plex channels, where the receive and transmit fre-

quencies are already the same. Note that your dealer may have mode provision for Talk Around channels by programming repeater and Talk Around frequencies on two adjacent chan-

nels. If so, the key may be used for one of the other Pre-Programmed Functions. 12 VX-P920/-P970 OPERATING MANUAL ADVANCED OPERATION FOLLOW-ME SCAN The Follow-Me Scan feature checks a User-as-

signed Priority Channel regularly as you scan other channels. Thus, if only Channels 1, 3, and 5 (of the 8 available channels) are designated for Scanning, the user may nonetheless assign Channel 2 as the User-assigned Priority Channel via the Follow-

Me feature. To activate Follow-Me scanning, first select the channel you want to designate as the User-Assigned Priority Channel and press the assigned program-

mable key. Then rotate the CH Selector knob to re-

call to the Scanning Start channel which has been programmed by your dealer to activate the scanner. When the scanner stops on an Active channel, the User-assigned Priority Channel will automatically be checked every few seconds; if activity is found on the User-assigned Priority Channel, the radio will switch between it and the Dealer-Assigned Priority Channel, if any. FOLLOW-ME DUAL WATCH To set up a Dual Watch frequency pair using the Follow-Me feature, select a channel using the CH Selector knob. Now press the assigned programmable key; pressing the assigned programmable key locks the current channel as the User-assigned Priority Channel. Now rotate the CH Selector knob to select another channel (not the Scanning Start channel). Your radio will now switch back-and-forth between the currently-selected channel and the User-assigned Priority Channel. During Follow-Me scanning (after you have pressed the key), you can set up the Dual Watch feature by rotating the CH Selector knob to another channel. The radio will then scan back and forth be-

tween the original User-assigned Priority Channel and the newly-selected channel. The Priority Channel you have assigned (before pressing the key) will be retained in memory until you change it. VX-P920/-P970 OPERATING MANUAL 13 ADVANCED OPERATION CALL/RESET While the DTMF Paging System This feature, if enabled, allows the user to change the 3-digit Page Call code, used to call other simi-

larly-equipped stations. Press the assigned program-

mable key, followed by the three digits representing the Page Call code of the station you wish to call. Three tones will be heard after the last key is pressed

(the new code will now be transmitted). The receiver squelch of the other station will be opened, and you can begin communication. While the 2-Tone/5-Tone Paging System This feature, if enabled, press the assigned program-

mable key to send a 2-tone/5-tone sequential tone. CALL 1 TO CALL 5 Press the assigned programmable key to send a 2-

tone/5-tone sequential tone group which is pre-de-

fined. OPTION SW2 Press the assigned programmable key to toggle the optional accessory 2 On and Off. Emergency The VX-920 series include an Emergency feature which may be useful for alerting another party moni-

toring on the same frequency as your transceivers channel. Press the assigned programmable key to initiate an emergency call. For further details contact your Dealer. AF MIN VR Press the assigned programmable key to reduce the audio output to the (lower) level programmed by your Dealer.

vironments. 14 VX-P920/-P970 OPERATING MANUAL ADVANCED OPERATION ARTS (AUTO RANGE TRANSPOND SYSTEM) LONE WORKER Press the assigned programmable key to toggle the Lone Worker feature On and Off. The Lone Worker feature is designed to emit an alarm for 30 seconds when the Lone Worker Timer (pro-

grammed by your Dealer) has expired. If the user does not reset the timer by pressing the PTT switch, the radio switches to the Emergency mode. TA SCAN Press the assigned programmable key to toggle the TA (Talk Around) scan feature On and Off. While TA scan is proceeding, the VX-920 will search both the transmit and receive frequencies. When a signal is encountered on the receive frequency, the VX-920 will pause until the signal disappears. When a signal is encountered on the transmit frequency, the VX-920 will check for activity on the receive frequency every few seconds (interval programmed by your Dealer). This system is designed to inform you when you and another ARTS-equipped station are within commu-

nication range. During ARTS operation, when the radio receives the correct ARTS signal, a short beep will sound. If you move out of range for more than two minutes, your radio senses that no signal has been received; three short beeps will sound. If you subsequently move back into range, as soon as the other station trans-

mits, a short beep will sound. DTMF PAGING SYSTEM This system allows paging and selective calling, us-

ing DTMF tone sequences. When your radio is paged by a station bearing a tone sequence which matches yours, your radios squelch will open and the alert will sound.
