Operating Temperature
The
DS
®
-
25 is designed for use at temperatures between -45°C and +85°C.
If you switch on whilst the handset is at temperatures above 85°C then the message "E9 PLEASE
COOL HANDSET" will be displayed and the unit will automatically return to standby mode. If the
handset is at a temperature above 85°C then remove it from the vicinity of the heat source
(usually the sun on the dashboard) to allow it to cool down.
If you switch on whilst the handset is at temperatures below -45°C then the message "E6
TEMPERATURE TOO COLD" will be displayed and the unit will automatically return to standby
mode. If it is below -45°C then apply gentle heat to warm it up. Placing it close to your body under
your coat is usually an effective way of warming it.
At temperatures below -20°C, LCD displays become slow to react and could therefore cause
confusion to the user. User communication will be made through the green and red Light Emitting
Diodes (LED) on the handset fascia.
Please note that the LED's are operational at all working temperatures and may be used instead of
the display screen if desired.
Handset disconnection
The handset is connected to the vehicle via a cable. It is possible to disconnect the cable from the
handset by firmly grasping the moulded connector plug and pulling it out of the socket. If you know that
the vehicle is likely to be exposed to extreme temperatures then you may wish to remove the handset
from the vehicle between uses. To re-connect, reverse the operation observing the fact that the plug and
socket must be correctly orientated in order to be able to insert the plug into the socket. However, some
Offender Programmes impose restrictions on this practice.
