utilities, and warns the operator with a series of flashing
asterisks on the display and an audible alarm,
characterized by a rapid warbling sound.

backlight is controlled by an ambient light sensor and
does not require adjustment by the user.
The transmitter’s LCD backlight is activated whenever
you press a key. The backlight will automatically switch
off after a few minutes.
4.12 Bluetooth wireless
All RD8100 locators feature a Bluetooth wireless module
as standard, providing the ability to connect to
compatible devices such as iLOC enabled transmitters
(Tx-5B or Tx-10B), PCs, laptops or handheld devices
running a compatible application.
Refer to Section 12 for further information about
Bluetooth wireless connections and how to pair your
devices.
NOTE: The RD8100 locator wireless features may be
subject to national and or local regulations. Consult your
local authorities for more information.

4.13 iLOC™ and SideStep™
iLOC is a standard feature of all RD8100 locators, and
lets you control a Bluetooth enabled transmitter (Tx-5B
or Tx-10B) remotely from your locator.
With iLOC you can adjust the frequency and power
settings, and use SideStep™.
iLOC commands are sent over a Bluetooth module that
can operate at distances of up to 450m / 1400ft in direct
line of sight.
SideStep changes the selected frequency by several
Hertz and automatically sets the locator’s locate
frequency to match the transmitter’s output frequency.
This can be used to eliminate unwanted interference.
See Section 13 for a detailed explanation of iLOC.
4.14 SideStepauto
™
The transmitter can be used to recommend a general-
purpose locate frequency for the intended locate task by
measuring the impedance of the target cable or pipe.
SideStepauto helps to improve locate accuracy by
determining the best signal. SideStepauto can also help
to prolong battery life.
SideStepauto operates only in Direct Connection mode.
