turns itself off. IMPORTANT: interrupting the initial charging cycle may seriously affect the ability
of the batteries ever to reach full capacity.
2.2.3 Charging the Detector Unit (DU)
NOTES:
The DU can be powered either by re-chargeable D–size NiCad batteries OR by D-size alkaline
batteries, both of which types are supplied with the unit. Only the NiCad batteries can be
charged using the following procedure. Using the charger with alkaline batteries installed in
the DU will result in damage to the unit.
There are three charging procedures:
(a) for charging NiCad batteries that are not completely exhausted (flat)
DU off.
(b) for charging NiCad batteries that are not completely exhausted (flat)
DU on.
(c) for charging completely exhausted (flat) NiCad batteries
The NiCad batteries are completely exhausted (flat) when the DU display
does not activate after the I/O button on the display panel is pressed with
the batteries installed.
There are two controls for the power supply to the DU:
1. The MAIN POWER switch (located in the battery
compartment and normally left ON – see Fig. 1 Right
2. For normal operational use the DU is switched ON and Off by pressing the button marked I/O
on the DU display panel / control keypad.
• DO NOT USE THE CHARGER WHEN ALKALINE BATTERIES ARE
INSTALLED IN THE DU – overheating and possible damage will occur!
• NEVER use carbon/zinc or lithium-based batteries AT ANY TIME!
• NEVER user or charge a mix of different types of batteries!
• Unpack the six (6) NiCad batteries and put them on one side. Locate the elongated
black plastic panel on the lower back spine (the battery compartment and main
power switch cover). Remove the panel using the large black knob. Now rermove
the two battery covers using a coin (twist 90° anticlockwise). Ensure the main power
switch in this compartment is OFF! Insert the batteries NEGATIVE (-ve) end first,
three to each battery compartment – see Fig. 2 on page 2-4 below.. Replace the
battery compartment covers (90° twist clockwise) and then switch the main power
