Battery Charging
To recover from ‘Sleep’ mode, the Smokehead should be put back in its Charging Cradle, and the
LED function observed.
2. Smokehead returned to Charging Cradle:
FAST CHARGE (2.5 flashes per second):
The Smokehead is in ‘Fast Charge’ Mode. The battery should fully charge within 1.5 hours.
TOP-UP CHARGE (1 flash per second):
The Fast Charge cycle has completed and the battery is being brought to full charge.
SLOW CHARGE (1 flash every 2 seconds):
The Smokehead battery is in ‘Slow Charge’ mode, the charging rate determined by either
Terminal Voltage or, Battery Cell temperature.
TRICKLE CHARGE (1 flash every 3 seconds):
LED Flashing ON/OFF shows the Smokehead battery is in ‘Trickle-Charge’ mode indicating that
the batteries are fully charged.
Fault Diagnosis:
FAST FLICKER (8 flashes per second or more):
The smokehead has detected poor charging contacts. Clean the contacts on both the cradle and
the smokehead feet and replace on charger.
LED NOT ILLUMINATED:
Return the Smokehead to Charging Cradle. LED should display according to Charging level
required.
LED NOT ILLUMINATED WHEN SMOKEHEAD IS ON CHARGING CRADLE:
Check that the Smokehead is correctly seated on the charging Cradle. The Smokehead has twin
connectors on each insulated foot, and may be connected either way round.
Check the Charging Cradle is connected to the 240 V AC Mains.
Check that the sprung connectors that transmit the Charging Current on the Charging Cradle are
clean and not stuck in a depressed condition.
Check that the Charging Connectors on the insulated mounts on underside of the Smokehead are
clean and free of dirt and obstructions.
To check the charging Voltage at the Charging Cradle: Connect a Digital Multimeter set to
measure up to 30V DC to the two charging Connectors on the charging Cradle, and depress the
Central Charging Switch. A Voltage of 28 V to 30 V DC should register on the Multimeter Display.
The internal battery pack has a finite lifespan and will need to be replaced periodically. This should
be carried out by a qualified Service Engineer.
There are no user serviceable parts in the Smokehead.
