TK-980/981
■
In Conventional System
If QT or DQT is set for the group, the groups, including
signalling, are scanned.
In case of the priority group is set in conventional system,
if a group scan (including group scan during a system scan)
temporarily stops (receiving) in a group that does not have
priority, a look back is performed to the priority group. Look
back is performed according to the look back time A and B
settings. If a call is received on the priority group, reception
immediately switches to the priority group.
4. Details of Features
■
Time-out Timer
The time-out timer can be programmed in 15 seconds
increments from 15 seconds to 10 minutes. If the transmit-
ter is keyed continuously for longer than the programmed
time, the transmitter is disabled and a warning tone sounds
while the PTT button is held down. The alert tone stops
when the PTT button is released.
■
Sub LCD Display
You can use 3-digit the display to display the system
number or group number. It is useful when the main (12-
digit) display indicates system, group name or other func-
tions.
■
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.
■
PTT ID
PTT ID provides a DTMF or MSK (FleetSync™ : Fleet-ID)
ANI to be sent with every time PTT (beginning of transmis-
sion, end of transmission, or both).
You can program PTT ID for each group. You can pro-
gram PTT ID as “on” or “off” when “DTMF” is selected for
the PTT ID type. You can program a PTT ID as “own”, “sel”
or “off” when “MSK” is selected for the PTT ID type. The
contents of ID are programmed for each transceiver.
The timing that the transceiver sends ID is program-
mable.
BOT : DTMF ID (BOT)/MSK ID is sent on beginning of
transmission.
EOT : DTMF ID (EOT)/MSK ID is sent on end of transmis-
sion.
Both : DTMF ID (BOT)/MSK ID is sent on beginning of
transmission and DTMF ID (EOT)/MSK ID is sent on end
of transmission.
■
Radio Password
When the password is set in the transceiver, user can not
use the transceiver unless enter the correct password.
This code can be up to 6 digits from 0 to 9 and input with
the key, and “SCN” key.
OPERATING FEATURES
■
Off Hook Decode
If the Off hook decode function has been enabled, re-
moving and replacing the microphone on the hook has no
effect for decoding QT/DQT and option signalling.
■
Timed Power Off
This function works as “Automatic Power Switch Off”.
Timed power off timer starts from the ignition-off. After
the timer expires, the radio will automatically turn off. The
timer will be reset if the ignition is turned on and off.
This function requires ignition-sense. Connect the igni-
tion-line to the 9-pin connector which is located at the rear of
the radio.
After the timer expires, press the power switch to turn
on the radio.
■
Horn Alert
Horn alert can be set to on or off for each group. If horn
alert has been set to YES for a group and DEC ID/QT/DQT/
MSK matches, the horn alert, HOR. is turned on and off.
The group for which the optional signalling is set works by
ANDing the decode ID/QT/DQT/MSK with the optional sig-
nalling.
Either continuous or non-continuous operation can be set
by the FPU. The horn alert port is enabled or disabled as
follows;
Off hook horn alert
Hook off
