Cobra Electronics 8166 - Manual (Page 3)

The security system is operated by remote
control radio keys. Two radio keys are
supplied with each Cobra 8165 Alarm
System. Always press the button for a full
ONE SECOND to allow the whole code to be
transmitted. The small LED on the radio key
will flash whilst the button is held down.
The Radio Keys should normally operate up
to 5 metres from the car but range can be
affected by other radio signals in the vicinity.
The Radio Keys are powered by a long life 3v Lithium battery
(type CR2032 or equivalent). With normal usage a new
battery should last between 3 and 5 years. Replacement
batteries can be obtained from your Cobra Dealer.
Low Radio Key Battery Indication
If the small LED on the radio key flashes irregularly or only
once when the operating key is pressed, instead of flashing
continuously, this indicates a low battery.
Each Cobra 8165 Alarm System has a unique PIN code which can be used for Emergency
Disarm and is required, together with one of the emergency override touch keys, for
programming replacement or additional radio keys.
Your PIN code is given on the card supplied with your Cobra 8165 Alarm System together
with the serial number of the system itself. Please keep this card in a secure place - not in
the car - and also make a note of these numbers for any second driver’s use.
Without the PIN code and emergency override touch key no additional or replacement
radio keys can be programmed into the system.
