When using an Entel VOX enabled audio accessory, your HT500 portable can operate totally hands free. All you need to do is talk and the HT500 portable will automatically transmit for you.

Scan/priority scan
The HT500 Series portables have the facility to scan for an active (or free) channel. When the channel is found, the radio will automatically select it channel 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 HT500 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.
