Explanation
If a carbon-type handset or carbon-type headset is
connected to the handset jack, the carbon wire
jumper straps, listed on the left, must be cut inside
the telephone. When a carbon headset is connected
to the BHEU, you do not need to cut the straps. See
Figures 7-7~7-9.
To turn off the handset receiver when the handset is
on-hook and a headset is used with the BHEU, cut
the "HEU" strap shown on the left.
Cut the "EX.POWER" straps only when external
power is connected to the second pair (pins 2 and 5)
of the telephone modular jack. See
MDF PCB Wiring, Figure 6-6 on page
Do not cut – for factory use only.
