Two low battery sounds are played and two red flashes on the LED PIOs are displayed periodically (every 60 s). Called IND-Battery2. Level 3 (below 3.4 V). Three low battery sounds are played and three red flashes on the LED PIOs are displayed periodically (every 60 s). Called IND-Battery3.

Walkie-talkie state. An intercom session with a receiver is active. Indicated by LED-Connect. Prioritized audio messages (e.g. navigation information from GPS) does not use a separate state. Instead the information is sent via walkie-talkie or AV. 3.3.5 AV State AV state may be entered from the Idle state.

IND-Success indication is issued when finished. The Idle stat is indicated by LED-Idle. 3.3.7 Pairing State Pairing state may be entered from the Idle state only. 1. Pairing state is entered when VOL+ is moved inactive to active state. 2.

The TI and NI are monitored continuously. 2. When both the TI and NI become inactive the intercom session with the first receiver paired with the base unit is terminated. 3. If the previous state was the Idle state or the MF is inactive the base unit is moved to Idle state. 4.
