Figure 7: Frequency Selection
There are 6 frequencies to choose from.
•
128Hz Low
•
1kHz Low
•
8kHz Medium
•
33kHz Medium
•
262kHz (93kHz Europe) High
•
200 kHz Alternate High Frequency
A 200 KHz frequency is available. It is set by
pressing on the 262Hz High Frequency button for ten
seconds. The transmitter will blink three LEDs rapidly
when the frequency is set. The LED over the 262 kHz
label will blink once every 5 seconds to indicate the
transmitter is on the alternate frequency of 200 kHz
rather than the labeled frequency of 262 kHz.
Note: The high frequency on European models is
93 kHz. The 200 kHz button on European models
will set the transmitter to 93,623 Hz. A long press
(greater than one second) on the same button will
set the transmitter to 93,696 Hz., to accommodate
older receivers which may be tuned to this variant
of 93 kHz.
4. Check the Circuit
More current gives a stronger signal. Less current
prolongs battery life. Signal strength measured by the
receiver is directly proportional to the amount of

current on the line. More current means a stronger
signal will be received by the receiver.
To prolong battery life and reduce the chance of the
signal "bleeding over" onto adjacent lines, use the
minimum amount of current needed to get a clear
reading on the receiver.
5. Adjust Current.
The power output for the chosen frequency can be
modified in five increments from low to high. Once
you have chosen a frequency, press the same
frequency
button
a
corresponding to the current power level will flash..
While it is flashing choose a power level by pressing
one of the frequency buttons. (Lower power settings
start on the left, higher toward the righ). When you
press one of the frequency buttons during the period
when the original light is flashing it will set the power
level. The beep rate will increase or decrease as
power is increased or decreased. (See "Variable
Output Power" on page 12.)
The approximate current levels of the power settings
are 4 mA,15 mA,50 mA,150 mA, and 600 mA. Actual
power
output
varies
(resistance, impedance and quality of connections).
When a current level is chosen, the transmitter will
adjust the voltage to try and produce the selected
current and lock it in. If the transmitter cannot
produce the current selected it will adjust down to the
next level.
The transmitter's maximum current and power output
depend on the circuit.
WARNING
If the transmitter is reporting low or no current (low
beep rate), the signal may be too low to be
detected by the receiver locator and inadequate for
tracing.
6. Check the Receiver
Confirm that your receiver is set to the same
frequency as the NaviTrack transmitter. Confirm the
receiver is picking up the transmitted frequency by
holding it near the transmitter and observing the
increase in receiver signal.
