Setting up Follow these
steps to get your Diverse handset 
ready for use
Warning 
1 Use only approved nickel-cadmium (NiCad)
rechargeable batteries. Never use other 
batteries or conventional alkaline batteries. 
Using such batteries could lead to a short 
circuit or destroy the battery casing. 
Recommended batteries should have a power 
rating of 600m Ah 1.2V. Batteries available 
from the Diverse helpline 0345 908070.
2 Do not try to use any power supply except
the one provided, other wise you may 
permanently damage your Diverse. It will also 
result in non-compliance with EN41003:1993, 
and will invalidate the approval given to this 
apparatus.
3 There is a slight chance that your phone
could be damaged by an electrical storm. 
We r ecommend that you unplug your Diverse 
from the mains power and telephone line 
socket during storms.
4 If you wear a hearing aid, please note that
the Diverse works by sending radio signals 
between the base unit and handset. These 
signals can interfere with hearing aids, 
causing a humming noise.
5 Diverse handset can interfere with other
electrical equipment e.g. answering machines, 
TV and radio sets, clock radio/alarms and 
computers if placed too close. It is 
recommended to place your Diverse handset 
at least one metre away from such appliances 
to avoid any risk of interference.
6 It is possible that the Diverse handset may
be affected by being near bodies of water 
(e.g. ponds, lakes, the sea). 
6

3 Charging the handset batteries 
for at least 16 hours
Before you use the handset, place it on 
the base unit or charging unit (available 
separately). The handset can be charged 
face up or down. Make sure that the 
contacts on the bottom end of the handset 
are touching both charging contacts. 
When the handset batteries are charging, 
the green CHARGING light comes on.
Normal battery charging time.
After charging your Diverse for the first 
time, normal charging time for the handset 
batteries is about 4-5 hours. Batteries warm 
up when being charged; this is normal and 
not dangerous.
Under ideal conditions, the handset batteries 
should give about 6.5 hours talktime or 
60 hours standby on a single charge. However, 
new NiCad batteries do not reach their full 
capacity until they have been in normal use 
for several days.
Battery low warning
flashes and handset beeps to warn 
you that the batteries are within 5-10 minutes 
of being completely f lat.

that you:
• Assign a number to each base station, 
from 1 to 4.
• Number each handset (1 to 6) 
registered at each base station.
• Register the handsets at base unit 2 
(and 3 and 4 if used) in the same order 
as used for base unit 1.
• Activate the display of the base unit 
numbers on each handset.
If however you move out of range of the 
displayed base unit, and within range of 
another base unit during a call you will lose 
your current call.
30
Handsets can only be used with the base units 
displayed on screen.
If you move out of range of the displayed base 
unit, and within range of another base unit, 
your radio link will be automatically set up. 
(Provided your handset has been registered
