Monitor Button

The Monitor button can enable or disable “GROUP MODE (CTCSS/DCS)” if programmed for that channel.

1) To enable “GROUP MODE”. Press and release the“MON” button: “SAT” icon is displayed. A Sub

Audible Tone mutes your speaker.

2) To Disable “GROUP MODE”. Press the “MON” button: “SAT” icon is not displayed. You are now

working in “Open Traffic”.

 NOTE: if “SAT” icon is never displayed, “CTCSS/DCS” tone is not programmed. “GROUP

MODE” function is not available.

3) Press and Hold “MON” button for three seconds, internal squelch will be disabled and your speaker is

un-muted. Press and release the “MON” button to restore the squelch to normal operating condition.

Transmitting

1) Ensure that the channel is not busy otherwise you will create interference.

2) Press the “PTT” button, the status LED will glow red.

3) Start talking at a normal voice level at approximately 2.5 inches from the microphone (keep the

“PTT” button pressed).

4) When you have finished talking, release the “PTT” button.

 Do not shout! It will not increase the distance you can transmit, but rather will make you heard

distorted.

 Do not release the “PTT” button before your message is over or start talking before pressing

“PTT”, otherwise your message will be “chopped”.

 A handheld radio does not allow you to talk and receive simultaneously, for this reason make your

messages short. When you are talking the other parties can not use the channel! Use common

sense.

 Your radio is programmed with a timeout timer which will automatically turn off the transmitter if

you talk longer than 90 seconds. In this case release the “PTT” and wait for few seconds, the radio

TX features will be automatically restored.

Adjusting Transmit Power

Your 70-440BP can transmit with two power levels according to the distance of your party’s station(s). We

do recommend, when possible, to use the Low power setting. This will increase the battery life and will

reduce the risk of interference with other stations not in your radio network that may be sharing the same

channel with you.

1) To change the channel's Power Output level from high (2 Watts) to Low (0.5 Watt), or vice versa,

Press and Hold “FUNC” key for about 2 seconds. A small "LOW" will appear in the lower left corner

of the display to indicate “Low Power”. High Power has no indicator.
