9. The “ON/Auto” Switch
In most cases, the AUTO position is recommended. The headset switch is automatically switched on,
when the telephone is on or the receiver is lifted.
The red LED in the MUTE key lights up or blinks for verification.
In rare cases, your telephone may only function with the headset switch in the ON position.
10. The MUTE Button
You can deactivate the microphone with the MUTE button. The LED flashes for verification. The
microphone of the normal telephone receiver is unaffected.
11. Connecting a Power Pack
Please ONLY connect using power packs approved by Hama!
Please observe that due to different systems, minimal electrical noise may occur when operating
with a power pack. Use batteries in such cases. The headset switch is extremely energy-saving.
Please observe the correct polarity and voltage setting on the power pack!
Currently approved power pack: Hama item number: 46594
