DigiTrak F5 Operator’s Manual xxxvii
Transmitter Battery Status
The battery status symbol at the bottom of the receiver’s depth mode screen
indicates the battery life remaining for alkaline batteries.
Because the battery status for a SuperCell battery will appear full until just before it is fully
depleted, you must track its hours of use.
Sleep Mode (Automatic Shutdown) / Power Off
All battery-powered DigiTrak transmitters go into sleep mode and stop transmitting to
conserve battery power if they are stationary for longer than 15 minutes. To awaken the
transmitter, rotate the drill string. If you are using an FPT, rotate the drill string approximately
a half rotation; an FPT will not awaken if it lands on the same roll position at which it went to
sleep.
A small amount of charge will continue to drain from the batteries while the transmitter is in
sleep mode. To conserve battery life, do not leave batteries in the transmitter when they can
easily be removed, and always remove batteries when the transmitter is not being used.
Note An FPT will continue to transmit for up to 20 seconds after the batteries
are removed. If you have removed the batteries and intend to restart the
transmitter in another frequency, wait until data has stopped displaying
on the receiver before reinstalling the batteries.
Transmitter Housing Requirements
For maximum transmitter range and battery life, the slots in the drill housing must meet
minimum length and width requirements and be correctly positioned. DCI recommends at
least three slots, each at least 1/16 or 0.0625 in. (1.6 mm) wide and equally spaced around
the circumference of the housing. For accuracy, slot measurements must be taken from the
inside of the housing.
Slots for long-range transmitters (15 in./38.1 cm long) must be at least 8.5 in. (21.6 cm) long
and begin at least 2 in. (5.1 cm) but not more than 3 in. (7.6 cm) from the front of the
transmitter:
Long-Range Transmitter Housing Slot Requirements
Long-range FPTs have the same slot requirements but additional housing requirements;
