Safety Considerations
This product and manual must be thoroughly understood before attempting installation and operation.
To do so without proper knowledge can result in equipment failure and bodily injury.
Caution: Before applying ac power, be sure that the equipment has be properly configured for the
available line voltage. Attempted operation at the wrong voltage can result in damage and voids the
warranty. See the manuals section on installation. DO NOT operate equipment with cover removed.
Earth Ground: All Datron products are supplied with a standard, 3-wire, grounded ac plug. DO
NOT attempt to disable the ground terminal by using 2-wire adapters of any type. Any disconnection
of the equipment ground causes a potential shock hazard that could result in personal injury. DO NOT
operate any equipment until a suitable ground has been established. Consult the manual section on
grounding.
Servicing: Only trained personnel should carry out servicing. To avoid electric shock, DO NOT open
the case unless qualified to do so. Various measurements and adjustments described in this manual are
performed in ac power applied and the protective covers removed. Capacitors (particularly the large
power supply electrolytics) can remain charged for a considerable time after the unit has been shut
off. Use particular care when working around them, as a short circuit can release sufficient energy to
cause damage to the equipment and possible injury.
To protect against fire hazard, always replace line fuses with ones of the same current rating and type
(normal delay, slow-blow, etc.). DO NOT use higher value replacements in an attempt to prevent fuse
failure. If fuses are failing repeatedly this indicates a probable defect in the equipment that needs
attention.
Use only genuine Datron factory parts for full performance and safety of this product.

More than 1 channel must be assigned to the memory scan list for
scanning to take place. Scanning can be viewed in channel mode or
frequency mode.
1. Turn the Channel knob to the F position.
2. Press SCAN.
The radio scans the memory list in a continuous loop at a speed
set in the Programmer (from 50 ms to 120 ms). The example
below shows an uninterrupted Memory scan (no activity
detected).
3-6 HH7700-MSOP
3: Radio Operation
When a signal is detected on a channel, the monitor icon is
displayed, the channel or frequency flashes and activity on the
channel is heard. Scanning pauses for 5 seconds unless tone
decoding is enabled on some or all channels causing the scan rate
to slow down as the radio decides whether or not there is
something worth listening to.
When the signal ends or 5.0 seconds is up, scanning resumes.
3. Press SCAN again to stop scanning.
Dual Watch Scan
Dual watch has two functions and is dependent on how the channel knob
is positioned. It is setup as follows:
To scan all assigned channel frequencies with a priority channel:
1. Turn the channel knob to the F position.
2. Press DUAL WATCH.
The radio begins to scan all of the channels that have assigned
frequencies at a speed set in the Programmer (from 50 ms to
120 ms). In the example below, channels 1, 5 and 6 are the only
Channel
Position
Description
FScanning alternates between all channels that are
assigned to a frequency and a programmed priority
channel. This function does not work if the assigned
Priority channel is also a Preset channel.
1 to 15 Scanning alternates between the chosen Preset channel
and the programmed Priority channel. This function
does not work if the chosen Preset channel is also a
Priority channel.

programmed frequencies and channel 12 is the priority channel.
After scanning the priority channel, the scan cycle continues with
channel 1.
When a signal is detected on a channel, the monitor icon is
displayed, the channel or frequency flashes and activity on the
channel is heard.
Scanning pauses for 5 seconds unless tone decoding is enabled on
some or all channels in which case the scan rate slows down as
the radio decides whether or not there is something worth
listening to.
When the signal ends or 5.0 seconds is up, scanning resumes.
3. Press DUAL WATCH again to stop scanning.
Note: If the radio finds something of interest on a non-priority
channel, it continues to monitor the priority channel. If the radio
finds something of interest on a priority channel, it stays there. If
something of interest is found on both a non-priority and priority
channel, the radio stays on the priority channel.
3-8 HH7700-MSOP
3: Radio Operation
To scan a Preset channel with a Priority channel:
1. Turn the channel knob to one of the Preset channels (1 to 15).
2. Press DUAL WATCH.
The radio begins to scan the radio looking for the Preset channel
and the Priority channel (setup using the Programmer) to monitor.
In the example below, the Preset channel is 5 and the priority
channel is 1.
When a signal is detected on a channel, the monitor icon is
displayed, the channel or frequency flashes and activity on the
channel is heard.
Scanning pauses for 5 seconds unless tone decoding is enabled on
some or all channels in which case the scan rate slows as the radio
decides whether or not there is something worth listening to.
When the signal ends, or 5.0 seconds is up, scanning resumes.
3. Press DUAL WATCH again to stop the scanning process.

Key Lock Feature
The key lock feature prevents the accidental pressing of radio buttons
with the exception of PTT and MONITOR.
To activate this feature:
1. Press MONITOR for more than 2 seconds. Doing so displays the key
icon .
The key lock status is retained when the radio is turned off.
2. Release the key lock by pressing MONITOR again for more than 2
seconds. The key icon is no longer displayed.
Power Save Feature
If no transmission or reception has occurred for 5 seconds, the receiver
switches from continuously on to periodically turning on and off based
on whether and how the radio is programmed. By reducing the amount
of time the receiver is on, battery life is extended.
The power save feature is set by the Programmer as follows.
•Battery Save On Timer:
Set to Disable or 200 ms to 1000 ms, at 50 ms increments
• Battery Save Off Timer:
Set to 100 ms to 500 ms, at 50 ms increments.
With this feature enabled, up to 500 ms of an incoming message can be
missed so in some cases the sender may have to repeat the call. However,
the resulting increase in battery life is usually worth this inconvenience.

3: Radio Operation
Back Light Feature
The back light is enabled using the Programmer and can affect the
display area and buttons on the radio in various ways:
• On After Key. The light goes on after any key is pressed (default).
It lights up for 1 second when the radio is turned on and for 5
seconds when the channel knob is turned or any other button is
pressed (pressing any key within this 5 seconds extends the light
5 seconds longer).
• Always on. The light is always on.
• Disable. No light (useful in combat situations).
Scramble Feature
The scrambler is a hopping type of rolling code encryption that must be
installed in your radio. A SCRAMBLE button must also be assigned by the
Programmer for this feature to work. For details about using this feature,
refer to the TVS-2-DT1 manual.
VOX Feature
VOX allows hands-free operation for voice detection and transmission.
A VOX button must be assigned by the Programmer for this feature to
work. When VOX is enabled, V is displayed. When scan is activated,
VOX is overridden.
The VOX status is retained when the radio is turned off.
CAUTION: Not to be used with the Whisper feature.
HH7700-MSOP 3-11
3: Radio Operation
Whisper Feature
Whisper increases the sensitivity of voice transmission. The validity of
its use must be taken into consideration before being programmed into
the radio. A WHISPER button must be assigned by the Programmer for this
feature to work. When Whisper is enabled, W is displayed. When scan is
activated, Whisper is overridden.
The Whisper status is retained when the radio is turned off.
CAUTION: Not to be used with the VOX feature.
Cloning a Radio
Programmed data can be copied between 2 radios.
1. Connect the cloning cable to the radios.
2. Place both radios into cloning mode by pressing MONITOR and ▲
simultaneously while turning the radio on. The following screen
is displayed on both radios.
3. Press P1 on the transmitting (master) radio.
A beep sounds when the transfer of data is finished. END is
displayed on the sending radio for 2 seconds followed by CLO-M.
After the receiving radio gets the data, CLO-M is displayed.
Note: If cloning fails, the radio beeps and ERR is displayed for 2
seconds followed by CLO-M.
