DM588 Digital Mobile Radio
This function enables the radio to send an emergency alarm if no operation (e.g. a keystroke) is performed on the
radio within a preset response duration. This function needs to be set using the programming software. This
function works as below.
1. If no operation is performed on the radio when a preset response duration is nearly up, the radio will give a
preliminary alarm.
2. When a preliminary alarm is given, you can press any key to cancel it.
3. If no operation is performed when the preset response duration is up, an emergency alarm will be sent
automatically.
5.11 Encryption (Digital Channel Only)
This function achieves encryption of voice or a short message to avoid interception by a user on the channel
using third-party software, so that secret communication is ensured. Encrypted signals can be transmitted via a
channel with encryption enabled, and decryption signals can also be received. This function needs to be set
using the programming software.
Every channel supports the following two types of encryption. The setting can be done by your dealer.
A sending radio and a receiving radio sharing an encryption key can decrypt a call or data from each other. The
radio cannot receive an encrypted call correctly if a different encryption type or encryption key is used on the
sending radio.
