If the battery icon is "blinking" (Low Battery indication), the Unit will automatically switch to Low
Power when transmitting in order to help prolong the Battery's operational life. In this case, two
short beeps will be heard when you press the “PTT” key before the radio transmits.
Scanning channels
Your 70-440BP has three types of scanning available. The most used is Normal Scan. This allows you to
scan all the channels you have designated in your scan list (see Creating Scan List). The next is scan with
a Priority channel. This scan allows you to select a channel that will be monitored more often than the
other channels while scanning (for this scan to work properly you must have at least 6 channels in the
scan list). The next scan is Dual Watch. This allows you to scan only two channels of your choice. You
must have more than one channel programmed in the scan list in order for your 70-440BP to scan them.
The advanced scan function of the radio allows optionally looking for carrier or carrier with “CTCSS” or
“DCS.”
Creating the Scan-List.
1) Scroll the channel list, channels which show the “•“ icon, are in the “SCAN” list.
2) Select the channel, which is to be added or deleted from the “Scan” list.
Adding and removing channels from the Scan list is not available during scanning.
3) Press “CALL” + “MON” button, the “•” icon will appear or disappear. (See step 1 above.)
Activating, Deactivating Normal Scan
1) Press the “CALL” button + key. You will see the channel numbers cycling continuously.
2) To stop scanning press the “CALL” button + key.
, If when deactivating Normal scan you press the “CALL” button + key by accident, the radio will
be in Priority scan. If you press the “CALL” button +
key to deactivate the Normal scan the
radio will now be in Dual Watch (as described later). In this case to deactivate both scans you must
first press the “CALL” button +
then press the correct buttons “CALL” button + key.
NOTE: If the Scan List has no channels, a low tone (error beep) will be heard when the “CALL” +
key is pressed, no channel will be scrolled in the display. At least two channels must be in the
Scan List for the Unit to be put in the SCAN Mode.
When a signal is received on a channel, the radio will stop scanning and the speaker will become
un-muted. When the activity on that channel ceases, the unit will automatically resume scanning.
If CTCSS/DCS have been previously programmed, the scanning will stop only if the received
carrier has the appropriate signaling.
If “PTT” is pressed during scanning, the radio will transmit on the first vacant channel. In case of no
activity, the Unit will automatically resume scanning.
Selecting a Priority Channel
One channel can be assigned as a “Priority Channel”. The scanning will look back at the priority channel
most frequently.
Current radio version only allows for PC programming of another priority channel.
