Operation Time
Using alkaline cells, typical operation time is from about 12
to 24 hours depending on sound volume and how often
the backlight is on. Other factors that affect the operation
time will include chemistry of the battery (many of the new
high performance batteries, such as the “Duracell
®
ULTRA”
last 10% - 20% longer than conventional alkaline cells
under high demand applications). Operation at lower tem-
peratures will also reduce battery life.
The NaviTrack II display can also show random symbols
when the battery power is too low to drive the internal
logic circuits correctly. This is remedied by simply putting
fresh batteries into the unit.
To preserve battery life the NaviTrack II will automatically
shut down after one hour of no key presses. Simply turn
the unit on to resume use.
Low Battery Warning
When the battery gets low, a battery icon will appear
in the map area on the screen. This indicates that the bat-
teries need to be changed and that the unit will soon
shut down.
Figure 10 – Display Low-Battery Warning
Just before complete shut down, there will be a non-in-
terruptible power down sequence.
NOTE! Voltage on rechargeable batteries may some-
times drop so quickly that the unit will just shut
down. The unit will turn off and restart. Just re-
place the batteries and turn the unit back ON.
Starting Up
After pressing the Power Key on the keypad, the
RIDGID

to have it available.
Set Up
Once the NaviTrack II is up and running, the next step is
to set up the frequencies that match the Sonde, trans-
mitter, or line to be located.
Each frequency is selected for use by choosing it from a
list in the Main Menu. If the box on the Main Menu for that
frequency is checked, the frequency is in Checked-Active
status.
Checked-Active frequencies are already selected for
use and appear in sequence by pressing the Frequency
Key . (For example, the Sonde frequency of 512 kHz
is available by pressing the Frequency Key.)
