2.Operation Features
The TK-7102 is a VHF FM radio designed to operate in
conventional format. The programmable features are sum-
marized.
3.Transceiver Controls and Indicators
3-1. Front Panel Controls
All the keys on the front panel are momentary-type push
buttons. The functions of these keys are explained below.
• POWER key
Transceiver POWER key. When the power is switched
off, all the parameters are stored in memory. When the
power is switched on again, the transceiver returns to the
previous conditions.
• CHANNEL keys
• MONITOR key (Programmable)
• key (Programmable)
• VOLUME UP/DOWN key
When the key is pressed, the volume level is increased/
decreased and repeats if held for 200ms or longer.
• BUSY/TX LED
The BUSY indicator (Green LED) shows that the channel
is in use. The TX indicator (Red LED) shows that you are
transmitting.
3-2. Programmable Keys
The FPU (KPG-70D) enables programmable keys to se-
lect the following functions.
• Emergency
• Key Lock
• Monitor
• Scan ON/OFF
• Talk Around
• Temporary Delete
• None
• Emergency
Pressing this key for longer than 1 second causes the
transceiver to enter the emergency mode. The transceiver
jumps to the programmed "Emergency channel" and trans-
mits for 25* seconds.
The transceiver disables mic mute while transmitting.
After finishing transmission, the transceiver receivers for 5*
seconds. The transceiver Mute* the speaker while receiv-
ing. Following the above sequence, the transceiver contin-
ues to transmit and receive.
* Default value.
• Key lock
Pressing this key causes the transceiver to accept entry
of only the [Vol Up/Down]*, [Key lock], Microphone [PTT],
[Monitor], [Emergency], and [Power] keys.
* Programmable
• Monitor
Used to release signalling (press once) or squelch (press
and hold for approximately two seconds) when operating as
a conventional. It is also used to reset option signalling.
OPERATING FEATURES• Scan ON/OFF
Press this key starts scanning. Pressing this key stops
scanning.
• Talk around
Press this key, the transceiver uses the receive fre-
quency and the tone for transmission.
The operator can call the other party directly (without re-
peater). Press this key again, the talk around function goes
off.
• Temporary delete
The "Add" channel contained in the scan sequence, and
"Delete" channel is not contained. In the scan mode, this
key switches the channel delete temporarily (Press and hold
for approximately one second).
When the transceiver is turned off, the transceiver exits
the scan or switches the scan function off.
• None
Sounds error operation beep, and no action will occur.
Use this function when the transceiver is required to be
more simple operated.
4.Scan Operating
■SCAN start condition
Two or more 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 programmed to the scan ON/
OFF function, the scan starts. The indicator next to the pro-
grammed key LED blinks.
■Scan stop condition
The scan stops temporarily if the following conditions are
satisfied.
1) A carrier is detected, then QT/DQT matches on channels
for which receive the QT/DQT is set by the programming
software.
2) A carrier is detected on the channels for which receiving
QT/DQT is not set by the programming software or when
the monitor (signalling cancel) function is activated.
■Revert channel
The revert channel is used to transmit during scanning
and set by the programming software (KPG-70D).
1) Selected channel
The transceiver reverts to the channel before scanning or
the channel that you changed during scan.
2) Selected with talkback
The transceiver reverts to the selected channel prior to
scan initiation.
However, if a call is received on a channel other then the
selected channel and PTT is pressed before scanning re-
sume, the transceiver "talks back" on the current receive
channel.
■Scan end
When you press the key programmed to the scan func-
tion during scan mode, the scan ends.
The indicator next to the programmed key LED turns off.
