The Loud Ringing Bell/Headset upgrade (HHEU) enables an external speaker (HESB) for the
Loud Ringing Bell feature and/or a headset to be connected to both series of digital
telephones.
Notes
There are two types of HHEUs: the HHEU1 (which has four versions, V.1~V.4) and the
G
HHEU2.
Both 2000- and 2500-series digital telephones require either an HHEU2 or a V.3 or V.4
G
HHEU1 for HESB operation; earlier HHEU1 versions are only sufficient for headset
operation only.
Only digital telephones equipped with an HHEU2 can be wall mounted. The HHEU2 is
G
identical to the V.4 HHEU1, except that the HHEU2 has longer wires to accommodate
wall mounting.
