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 to be charged internally. Because the transmitter’s battery meter was calibrated for alkaline batteries, they will not be as accurate in calculating the remaining battery life when using rechargeable batteries.

Note, Carbon-zinc batteries are not recommended.
