OPERATION
OPERATING TIPS
General Tips: The microphone’s sensitivity is largely omnidirectional.
Presence of keys may affect the broadcast range and cause some irregularity in range with the
Key Fob’s orientation depending on where the keys fall. Ideally keys should point away from the
unit. It is recommended to keep metal objects other than attached keys away from the unit.
If buttons are pressed, the Vibrator Motor feedback will appear as momentary noise in
recordings.
The Key Fob is tuned at the factory to the customer’s specified frequency. The user can change
that frequency via the programming software but it is not recommended that it be changed
beyond ±1MHz of the factory-programmed frequency.
Fixed (audio) Gain mode, set in unit configuration, is recommended for scenarios where
environmental noise conditions are not optimal for AGC.
Handheld use Tips: Do not cover the microphone with your fingers or thumb. Hold in such a
way as to prevent keys from jangling.
Concealment in clothing: If the T-2765-KF is concealed in clothing the user is wearing, it
will be susceptible to clothing noise, and reduction in audio sensitivity. If keys are attached,
these may likewise generate noise in the recorded and/or transmitted audio if moved. The area
of clothing where the Keyfob is located should be kept as still as possible

TIP: Cold batteries shorten the operating life of the unit. A 3 hour life (Transmitting
& Recording) at room temperature may be shortened to just minutes at the extreme
lower temperature of -30°C.

Additional Operational Notes: The T-2765-KF operates on one AAA 1.5V Lithium battery.
A fresh battery will operate the unit (transmitting & recording), at room temperature, for 3
hours.

NOTE: Always turn the unit OFF and
remove used batteries when not in
use. It is imperative to discard partially
used batteries, as their remaining
life is not predictable. Always start
an operation with a fresh Lithium
battery.

TIP: Attach (only) one car key onto
Key Fob to minimize jingling noise
and metal-RF antenna interference.

NOTE: Regardless of the operating
mode, after a significant shock event
it is recommended that the user push
the Transmit button and confirm
the current operating mode from
the vibrator feedback. If necessary,
re-set the mode as required using the
buttons (page 5).
