If this function has been previously activated in the transmitter settings, simply turn off the transmitter and all receivers in the group will turn off automatically.

It is recommended to use the sequential method (FIFO – First In, First Out), i.e., assigning channels in order: 1, 2, 3, 4, etc. This method minimizes the probability of interference because adjacent channels do not use neighboring frequencies.

You can also divide the available pool of 160 channels, e.g., channels 1-80 for groups with reservations and 81-160 for the remaining ones.

The charger allows simultaneous setting of the same channel for all devices.

1. On the charger control panel, select the channel number using the ▲/▼ buttons and confirm with the middle button.
2. After synchronization is complete, the LED on the device will light up blue for 10 seconds (success) or start flashing red (error).
3. Make sure all devices have batteries inserted during this process.

A flashing red LED indicates a charging problem. The device should be checked immediately:

• Whether the device contains appropriate rechargeable batteries (disposable batteries are not allowed).
• Whether the batteries are inserted correctly (+ to +, – to –).
• Whether the charging contacts are clean.

Delay in checking may cause device damage not covered by warranty.

Receivers have an automatic shutdown function to save energy. The device will turn off automatically if it does not receive a signal from the guide's transmitter for 20 minutes. It may also turn off when the guide turns off their transmitter if the remote shutdown function is active.
