Powering the detector
The detector can be powered either from internal batteries or from an external power supply.
In the case of internal batteries, 5 AA cells are used. Alkaline batteries or rechargeable NiMH
cells are recommended – please note the polarity as indicated in the battery compartment! To
open the battery compartment lid, remove the lock screw using a screwdriver, a small coin or
similar. An external power supply or battery of 7-10 V DC can also be connected to the DC
jack. When external power is plugged in, the internal batteries are automatically disconnected.
The center pin of the DC jack is the positive pole of the power supply, as shown on the panel
label. The Main Power switch disconnects the battery or external power supply when set to
OFF, to avoid unintentionally switching the detector on. When this switch is set to ON, the
detector can be switched on by pressing the ON/OFF key for at least 1.5 seconds. To switch
the detector off, press the ON/OFF key for 3 seconds.
In order to constantly maintain power to the real-time clock and some other parts of the
detector, a small rechargeable battery is incorporated in the detector. This battery is
automatically charged from the regular batteries/power supply. The rechargeable battery will
keep the real-time clock running for about one month also when the regular power
supply/batteries are removed.
Caution. Carefully note the polarity of the batteries and/or the external power
supply. Reverse polarizing the supply voltage as well as exceeding the maximum
voltage may cause permanent damage to the detector!
Never allow any of the battery terminals or battery clips of the D1000X to get in
contact with the metal housing of the detector, either directly or through a metal
object. This may happen e.g. if the batteries are removed by means of a small screwdriver. If
you need to use an aid to remove the batteries, you should use an electrically insulated (i.e.
non-metal) object. Never use batteries with a damaged insulation layer over the housing. If
the metal housings of two adjacent batteries make contact, one or more batteries will be
short-circuited. If any of the above conditions occurs, damage to the detector and/or batteries
may result. The batteries may also become very hot, causing the danger of personal injury
and/or fire.
Battery handling precautions. Incorrect use or handling of the batteries can
cause them to leak or burst and create the danger of fire and personal injury as
well as damage to the detector.
Remove the batteries from the D1000X if you do not plan to use it for more than
two weeks.
Never recharge batteries, never allow direct connection between two ends of a battery and
never try to take batteries apart.
Do not expose batteries to direct heat or dispose of them by burning. Doing so can create the
danger of explosion.
Never mix batteries of different types.
Dead batteries are susceptible to leakage, which can cause serious damage to the D1000X.
Remove batteries from the detector as soon as you notice they are dead.
