Loud Ringing Bell/T001B Headset Upgrade (HHEU)

The Loud Ringing Bell/Headset upgrade (HHEU) enables an external speaker (HESB) and/or
a T001B unit and/or a headset to be connected to the electronic telephone. The HESB and the
T001B allows a loud ringing/flashing device to be activated with the ringing of an electronic
key telephone.
Notes
There are two types of HHEU: the HHEU1 (which has four versions, V.1~V.4) and the
HHEU2.
Only electronic telephones equipped with an HHEU2 can be wall mounted. The
HHEU2 is identical to the V.4 HHEU1, except that the HHEU2 has longer wires to
accommodate wall mounting.
A Toshiba HESC-65 or HESC-65A cable is required to connect the HHEU in an
electronic telephone to the HESB. Refer to
installation procedures.
All HHEU versions and types, except for V.1 HHEU1, are compatible with the Speaker
Off-hook Call Announce upgrades (HVSU2 and HVSU/HVSI).
