Notes

●There are two types of HHEUs: the HHEU1 (which has four versions, V.1~V.4) and the HHEU2.

●2000-series digital telephones require either an HHEU2 or a V.3 or V.4 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 identical to the V.4 HHEU1, except that the HHEU2 has longer wires to accommodate wall mounting.

●A Toshiba HESC-65A cable is required to connect the HHEU in a digital telephone to the HESB.
