MK3 CDT(b) Programming & Operation.
The Mk3's CDT(b) unit has many advanced features:
• Rechargeable battery with a minimum of a 3000 shot
capacity
• Automatic safety charging interlock feature
• Auto-safe feature if gun is left unattended
• User programmable shot counter with automatic reminder
• User programmable power adjustment
• User programmable magazine capacity counter
• User programmable on/off safety warning light
• Key operated isolating switch to allow authorised use only
• Low unlocked operating current in FIRE condition
• Settings remain programmed even if the battery is allowed
to drain
The unit will not lose its programmed settings even if the gun is
left switched on and allowed to drain the batteries completely.
Battery: A maintenance-free 12-volt rechargeable battery is
fitted, identifiable by a charging socket at the rear of the trigger
guard. The unit should be recharged every 3-5,000 shots or
when the red display light flashes to indicate ‘low battery’.
CDT(b) Battery Charging.
The unit has integral nickel-metal-hydride batteries, which have
a minimum life of at least 1000 charging cycles or 5 years
when being continuously charged. The batteries will provide a
minimum of 3000 full power shots with a typical capacity of
5000 shots at the UK muzzle energy limit. The on-board
charging circuit is current limited and can be left on indefinitely
with a charging time of typically 14 hours, the batteries can be
“topped-up” at any time without degrading the batteries’
capacity.

When the 15V unregulated power adapter is plugged in the
gun’s yellow light will flash every second to indicate charging.
The safety switch should be in the safe position before
charging.
Gun Operation and Programming.
The features of the gun and the associated programming of
these items are described below.
NOTE:
The gun is designed with a safety interlock that will not allow it
to fire with the trigger pulled when switching the safety catch to
FIRE to arm the gun. This safety feature also allows the user to
enter the programming mode of the gun.
Auto-safe Feature: The gun is fitted with an auto-safe feature
that will put the gun into an inert condition if the safety catch is
left in the FIRE position for over 30 minutes after the last shot
fired. The gun will beep and flash every 30-seconds to remind
the user to switch the gun to the safe condition. This condition
is simply reset by switching the safety catch to SAFE then to
FIRE. If the gun is left in the auto-safe inert condition, the
batteries will slowly discharge.
Magazine Counter and Operation: The magazine counter
operates by beeping and blinking twice after 10 shots,
representing the 10 shot capacity of the magazine. The
magazine counter is set to 10 shots and cannot be altered.
Should the counter get out of synch with the magazine, for
instance after a “dry” shot is accidentally fired with an empty
magazine, then the counter can be reset easily by the shooter.
If the magazine counter and shot counter coincide to provide
warnings, 6 beeps and blinks will be given indicating both
events.
