Battery Charge Level
To show the battery level press and hold in the button on the front panel until the yellow
battery light shows along with a number of red lights. The number of red lights indicates the
battery charge:
• 4 red lights = fully charged
• 3 red lights = good level of charge
• 2 red lights = medium level of charge
• 1 red light = low charge
• Yellow battery light flashing = discharged
After a couple of seconds of indicating the battery level all the lights will go out.
NOTE: If the battery is left in a discharged state then the unit will go into hibernation mode
and the background programs no longer run. When the button is pressed, depending on the
battery depletion level, the battery light may flash a few times or will not come on at all. The
user boost program will not start. It is necessary to recharge the unit to make it active again.
Putting the Unit into Sleep Mode
When the unit is not being used it can be put into sleep mode to save the battery charge.
To put the unit into sleep mode press and hold in the button until the battery level is shown,
then keep pressing the button until all the red indicator lights come on and then go out one
at time in a counter clockwise direction, then release the button. While in sleep mode all the
background programs are stopped. To wake the unit from sleep press and hold in the
button until the red indicator lights come on one at a time in a clockwise direction and then
release the button. The background programs will then operate normally.
Charging the Battery
The built in rechargeable battery is charged by
inserting a micro USB lead into the socket in the
side of the unit and connecting the other end to a
USB charger or USB port on a computer. To open
the USB port dust cover insert a small screwdriver
into the grove as shown and gently lever it open.
When charging the yellow battery light on the front
panel is illuminated and stays illuminated for as long
as the charger is attached.
To check the battery level during charging it is best
to disconnect the charging lead, wait a few moments
and then hold in the button on the front panel until
the battery light shows. A fully charged battery (four red lights) gives at least a month’s use.
It is recommended to charge the unit until it is fully charged (four red lights).
The time required to charge the battery will depend on how discharged it is. If the battery
level is at two red lights then a full charge takes around 7 hours. If the battery is fully
discharged (flashing battery light) then a soak charge of 20 hours is recommended.
