4 Once you have selected the mode you want, press
the key to confirm
5 Press and hold the key to select the new setting
and exit the menu
6 Press the key once to send the settings to the
transmitter
NOTE: Once you have stored the transmitter power
setting in the locator, the locator will change the
transmitter to that setting when you change the
frequency with the locator.
Sleep / wake the transmitter
To help you prolong battery life you can put the
transmitter in standby mode (sleep), and reactivate it
again, using the locator.
To put the transmitter into standby mode, set the TXOUT
menu on the locator to STDBY using the “Changing
transmitter power output” procedure described above in
section 13.2
This will disable the transmitter output.
To re-activate the transmitter output, select any power
mode from LOW to BOOST using the same procedure.
If the process fails, you may be out of range or there may
be an error in the connection. Move closer to the
transmitter and retry the procedure. If the connection
continues to fail, return to the transmitter and reset the
connection using the procedure described in Section
12.7
12.3 SideStep™
If you are using a preferred locate frequency and having
difficulty locating the utility, interference could be
affecting the locate signal. SideStep allows the locator to
change the locate frequency by several Hertz.
This ‘new’ locate frequency can be sent via the Bluetooth
connection to the transmitter and will automatically
change the transmitter frequency to match the ‘new’
locate frequency.
To step the frequency:
1 On the locator, select the frequency you want by
pressing the key until the frequency is displayed
on screen
2 To step the frequency, press and hold the key
until STEP appears on the LCD
3 Press the key to send the SideStep command to
the transmitter
4 If the command is sent successfully, an asterisk (*)
will appear on the locator next to the frequency and
STEP will appear on the transmitter below the
frequency
Repeat this process to disable SideStep
Finding a good ground point
When using a Direct Connection, it is important to get
the best possible grounding for the transmitter. This
provides the lowest resistance ground path and the best
output signal. If it is not possible to use the ground stake
the following are examples of good alternative ground
points:
Metal manhole covers
Metal drainage grates
Metal railings
Metal fence posts
12.4 Double-ended connections
Large diameter water pipes and gas distribution pipes
that are laid in sections sometimes have insulated joints
between the sections and can be difficult to locate using
a single ended connect. This is because when using a
single ended connection ground return, signals can often
cause confusion by returning to the transmitter along
other lines. The problem sometimes occurs when return
signals appear stronger than on the target line, usually
because the target line is deeper than the line carrying
the return signal, or the return path may be a better
electrical conductor than the target line.
Applying a double-ended transmitter connection is a
useful technique for positively tracing and identifying a
target line in a situation such as a heavily congested
industrial site, provided there are access points at each
end of the line.
Making a double-ended connection
Connect the transmitter to an access point on the target
line. The transmitter ground is connected with a long
cable to another access point further along the line. A
complete circuit is achieved without using ground as a
current return path. The long cable should be kept as far
away as possible from the expected route of the line.
This method of applying the transmitter signal is ideal for
positive identification of a target line. When a connection
has been made to two points on the same line, the same
level of current should be detectable around the circuit.
The locator display should remain constant if the depth
of the line does not change.
