Note, Though the direct transmission of the encryption code from the transmitter to the receiver is
faster and secure, since it is done at very low power in close proximity to the receiver, some users may
want to make sure that the code is never transmitted –thus the ability to enter it manually. Also,
for redundancy, in some cases the user might want to have two receivers in place holding the same
encryption code for the transmitter, with the second one as a backup.
To change to a new encryption code, when using a currently encrypted transmitter with another
receiver or desiring a fresh code, first go to the [CRYPTO] page on the transmitter. Using the
ON/
MUTE or VALUE button, change the setting from [ON] to [OFF] and press SELECT to cancel the
previous code. Then hold
SELECT to re-enter setup mode, go to [CRYPTO], and select [ON] again.
Follow the same procedure as before to view the code on the transmitter and transfer it automatically
or manually to the receiver.
During the operation of the system, if the receiver is receiving a signal from a transmitter that is
encrypted, and the matching code has been stored, a lower-case letter c will appear on the upper right
corner of the display. If the correct code is not in the receiver, or encryption has been turned off at the
receiver, the display will read [BLOCKED]. Audio cannot be received until the code has been entered
into the receiver, or a new code has been generated at the transmitter and transferred to the receiver.
Battery Level Indicator Functions
Line 6 transmitters contain battery level indicators that can accurately assess the remaining battery life,
and show this information on both the transmitter and the associated receiver. These indicators are
calibrated to commercial alkaline batteries, and can also provide useful information when used with
rechargeable batteries.
When the transmitter is turned on, the bottom line of the display will show the remaining battery
life in hours and minutes, with a battery icon next to the time. The remaining battery life is shown in
increments of twenty minutes (Hours:20). The initial time indicated just after the transmitter is turned
on, and for the first few minutes, will often show more time than is actually remaining – this is due to
the characteristic of alkaline batteries to temporarily increase in voltage for a short time after a period of
rest. For best accuracy, wait about twenty minutes after transmitter turn-on to rely on the time indicator.

On the receiver, the remaining battery life will be shown on the display in the lower left-hand corner of
the main page, and changes in sync with the transmitter’s indicator. In addition, the middle 5-position
LED ladder indicates remaining battery life in one-hour steps. When remaining battery life is more than
five hours, all five LEDs are lit, with between four and five hours left, four LEDs are lit, and so on. When
less than one hour of battery life remains, the bottom LED will turn from green to red – and will begin
to flash in the last 40 minutes of life.
NiMH (nickel metal hydride) batteries in the 2400 – 2800 mAh range are recommended as rechargeable
batteries to use with the THH12 and TBP12 transmitters. Make sure that the batteries fit properly in the
battery compartments to prevent damage, since these batteries can vary in diameter and length. They
need to be charged in the correct external battery charger; the transmitters are not designed for batteries
