1. Product information
Congratulations on purchasing the GN9120/GN9125. The GN9120/GN9125 is a wireless headset solution, made
up of a cordless headset and a base unit that is connected to your desk telephone. The GN9120/GN9125 gives
you full mobility, hands-free convenience and superior sound quality for your telephone conversations.
Checking product readiness of the GN9120/GN9125 (for RHL mode only)
If the headset is in RHL mode (connected with the GN1000, or connected via a
handset - or via a headset interface, not an EHS = electronic hook switch) and you
lift the headset from the base, the Online indicator will light up on the base.
If the green link-up indicator does not light, check the wiring connections on the
base unit and ensure that the power adapter is connected. If the on-line indicator
on the headset does not flash continuously, replace the headset in the base unit and remove it again.
Battery charging and use
When not in use, place the headset in the base unit to charge the battery. Ensure the link-up indicator is not
lit. If the link-up indicator is lit after placing the headset, remove the headset from the base unit and place
it in the base again. If battery charge is too low, a beep will be heard in the headset every 20 seconds.
