Entel HT-446 [9/30] Using your radio

Using Your Radio

Button Key Beeps

The radio will emit a short confirmation beep when pressing any of the function buttons. This

confidence tone confirms the button has been correctly pressed (key beeps may be disabled by

your dealer).

Channel Monitor Button (Dealer Programmable Function)

Tone/squelch defeat disables both CTCSS and DCS tones used and opens the squelch on the radio.

This will allow you to monitor any transmissions taking place that are not on the same

CTCSS/DCS tone on the channel you have selected and listen to any weak signals that may be

breaking up. When activated, you will hear either a rushing noise or any other channel users.

Turning Your Radio On

Turn your radio on using the on / off power button on the front of the radio. The radio will

“beep” and the LED will briefly illuminate yellow. (The beep may be disabled, if required, by your

Entel approved dealer).

Making a Call

Before transmitting on your radio, first ensure that the channel is not in use (yellow or green busy

LED will be illuminated and audio may be heard from speaker). To transmit press and hold the PTT

button on the side of the radio and speak clearly 25-50mm from the microphone. Release the

button to receive.

Transmit Time Out Timer (T.O.T)

A transmit time out timer is enabled on your radio. This will prevent the radio from transmitting

continuously. The maximum transmit duration is set to 90 seconds. If the transmit button is

pressed for this duration, the radio will generate an alert tone 10 seconds before automatically

ending the transmission, when a continuous tone will be emitted (the T.O.T. duration is dealer -

adjustable).

Panic Alarm Siren

The radio has a local panic alarm button, which, when pressed will emit a loud piercing siren from

the radio’s loudspeaker. To operate the local panic alarm, press the orange function button on top

of the radio for a minimum of 2 seconds. To cancel the alarm, simply turn the radio off.

Button Lock (Dealer Programmable Function)

A button lock feature is available to lock the channel control and other side / top function button

modes (except panic alarm). If available, press the assigned button to turn button lock on / off. If a

long button press is used to enable button lock, when unlocking, an error tone will be heard until

the button lock disables.

Low Battery Warning

Alerts you when the battery needs to be recharged. A ‘beep-beep’ audible alert every 20 seconds

and flashing red LED will indicate the battery is towards the end of its duty cycle and needs to be

charged (see battery care on page 4 for information on battery life warning alerts).
