Speaker
An audible indication of signal strength is also provided. The pitch of the sound will increase with
increasing signal strength. However, the volume is determined only by the VOLUME control. See Section
III - "Operation" - "Gain"- for additional hints on the effective use of the signal strength indicators.
Transmitter
The transmitter's frequency setting is performed automatically via the RF link at the receiver. The user
needs only to plug in the conductive clips, optional inductive clamp, or nothing (to operate in inductive
mode), then turn the transmitter ON. Turning the transmitter ON/OFF cannot be performed remotely from
the receiver.
Controls
With only three controls plus the ability to change frequencies from the receiver, the TraceMaster's
transmitter is very simple to operate.
ON/OFF - This is a momentary push-button switch that toggles the power to the transmitter on and off.
When power to the transmitter is ON, the nearby green LED will illuminate and remain ON.
NOTE: The ON/OFF switch needs to be pressed until the green LED illuminates, then released, to turn the
unit ON. Press the switch again until the green LED goes off to turn the unit OFF
NOTE: Power to the transmitter must be ON before the receiver is able to communicate with the
transmitter through the RF Link.
SHOW STATUS - In order to conserve battery power all LED's (except "Power ON" and “Battery”)
remain OFF unless this switch is pressed (see LED Indicators section). Press and hold this switch to
display LED indicators. In addition, when this switch is pressed and the transmitter is in conductive mode
and operating at 575 Hz, 8 kHz or 82 kHz frequency, the transmitter will measure the amount of current
being delivered through the conductive clips. When the receiver requests the status of the transmitter via
the remote link for the first time after pressing this switch (remember that the receiver interrogates the
transmitter every 10 seconds); the transmitter will include the value of the current measured in its response.
The value will subsequently be temporarily displayed on the receiver's LCD. See Receiver/LCD
Display/NUMERIC DISPLAY section for additional information.
SELECT - Press to manually select an operating frequency or to place the transmitter in the "Passive"
mode. Each press advances the frequency/mode as follows: Passive >> 575 Hz >> 8 kHz >> 82 kHz >>
455 kHz >> Passive, and so on. However, in induction mode the 575 Hz frequency and the 8 kHz
frequency are skipped (there is no induction mode at these frequencies). In addition, while using the
optional inductive clamp all frequencies not supported by the clamp will be skipped.
NOTE: The only reason to use the manual selection of a frequency is in the event a remote link with the
receiver fails to be established due to environment conditions (distance, obstacles, etc.), or a broken RF
antenna. When the remote link is established it ALWAYS takes precedence over the manual selection. In
some cases it is necessary to press the FREQ control in the receiver to synchronize the receiver and
transmitter units. See Section III "Operation" for additional hints.
LED Indicators
The transmitter has three LED Indicator sections on the front panel. They are labeled REMOTE,
FREQUENCY, and STATUS/MODE. In order to see these indicators the "SHOW STATUS" button must
be pressed and held, as explained in the previous section. The only exception to that rule is when the
