1.3.4.1 Headset (ER) for AlphaConnect P211/P220/P411/P421
All communication stations can connect a headset with a PTT button.
The headset cable (10 or 20-meter cable) can be taken directly into the stations via one of the PG glands or the optional
water tight headset connector set can be used.
The water tight headset connector set, which can be ordered separately, makes it possible to disconnect the headset
and stowed when not in use or easy to replace when worn out.
• CAUTION!
• The connector is NOT water tight when left open, so it is important to mount the cover properly when the
headset is removed, to leave it tight and closed for moisture. Failure to do so can reduce lifetime.
