Features
General
Keylock
To avoid accidental operation, your radio’s keys & controls can be locked by the user or, if set, automatically by the radio.
VOX hands free (with audio accessory)
When using an Entel VOX enabled audio accessory, your HX portable can operate totally hands free. All you need to do is talk and the HX portable will automatically transmit for you.
Scan/priority scan
The HX400 Series portables have the facility to scan for an active (or free) channel. When the channel is found, the radio will automatically select it for you. Priority scan will allow you to select one channel in the scan list that is treated as a “Priority”. It will be checked more frequently than all other channels in the list.
Programmable channel monitor button
If you have channel protection enabled on your HX400 portable, all signals other than your own networks will be filtered out. This can be temporarily disabled allowing you to monitor all signals on your channel.
Talkaround
Some radio systems use a “repeater” to increase the system’s range. However when you go outside the range of the repeater, communication with another radio is not possible, no matter how close you are. Talkaround enables you to talk directly with another radio, bypassing the repeater.
Individual & Group Calling (advanced models only)
Entel’s advanced 5-Tone Selcall & MPT1327 Trunking models provide Individual, Group & All Call. The radio’s contact list can be used to select the person to call as well as speed dials.
