GTR SPRINTCAR BLEEDERS User manual

BATTERIES
1 x 9 volt battery is required in each unit,
these can be either conventional throw
away batteries or rechargeable. Battery
voltage is displayed on main screen
however due to the option of conventional
or throwaway batteries the voltage differs
between the two. Therefore, this will need
to be monitored between different types
of batteries to get an accurate reading.
To install battery:
- Remove battery-retaining cap (shown
in figure 1) using 3/32 allen key.
- Install battery into housing
(figure 2a & 2b).
- Re-fit battery-retaining cap ensuring
cap screws are firmly tightened.
