T6M SERIES MOBILE SERVICE MANUAL – SM/16/1.0
It may be that the mobile does not transmit when you press the PTT button. This may
happen if there is a mobile fault or if transmitting is inhibited. In either case, the red Tx LED
will not light. If the mobile is programmed to produce warning sounds then you will hear a
warning sound. If there is a fault, a Fault Code is displayed whilst the PTT button is held
down. Fault Codes are described in Section 5.7. Transmit inhibit options are described in
sections 5.3 & 5.7.
A mobile may be programmed to transmit indefinitely, or to limit the duration of a
transmission. If transmission time is limited then mobile produces warning beeps 10
seconds before the end of the transmission. When the allowed transmission time is reached
the mobile stops transmitting, the red Tx LED goes out, and a warning sound is produced if
warning sounds are enabled.
5.2.2 Priority mode
Priority mode gives you quick access to your most frequently used channels. Up to 15
channels may be programmed into the mobile’s priority channel list. Select priority mode by
pressing the PRI button.
Priority mode operates like normal mode with the following exceptions.
•
Every few seconds the display shows “P” to remind you that you are in
priority mode.
•
Channels are selected using the SEL
é
and SEL
ê
keys.
•
Display blanking in priority mode causes the display to show a blinking “P”
rather than a bar.
You may leave priority mode in one of three ways.
•
Press PRI to return the previous mode (normal or scan).
•
Press CH
é
or CH
ê
to go to normal mode.
•
Press SCN to go to scan mode.
5.2.3 Scan mode
In scan mode the mobile scans a range of predefined channels looking for a busy one. A
busy channel is defined as a channel with a received signal strength greater than the squelch
threshold. A mobile may be programmed with up to 15 scan groups, with up to 15 channels
in each group.
When the mobile finds a busy channel you will be able to listen to that channel. What
happens next depends on the way the mobile is programmed. It has two possible seek
modes, “Hold” and “Pause”.
If Hold mode is programmed then the mobile remains on the channel until you press the CH
é
button to resume scanning.
