Shure Rechargeable Battery Care and Storage
Proper care and storage of Shure batteries results in reliable performance and ensures a long lifetime.
• Always store batteries and transmitters at room temperature
• Do not allow battery voltage to drop below 3 volts
Preparing Batteries for Long-term Storage
When storing batteries for periods longer than one month, keep the voltage level at approximately 40% of capacity. Maintaining a voltage of 40% of capacity protects the batteries and
places them in an ideal condition for long-term storage.
During storage, check the battery voltage every 3 months and recharge any batteries to restore the voltage level to 40% of capacity.
Audio Signal Encryption
When encryption is enabled, the receiver generates a unique encryption key which is shared with a the transmitter during an IR sync. Transmitters and receivers that share an encryption
key form a protected audio path, preventing unauthorized access from other receivers.
Encrypting a Single Transmitter to a Single
Receiver
1.
From the receiver menu: DEVICE UTILITIES > ENCRYPTION > ON (Auto)
2.
Press ENTER.
3.
Perform an IR Sync to share the encryption key with the selected transmitter.
Encrypting Multiple Transmitters to a Single
Receiver
Multiple transmitters can share the same encryption key, allowing them access to a single
receiver. Use this method if you have multiple instruments or wish to use a combination of
handheld and bodypack transmitters.
1.
From the receiver menu: DEVICE UTILITIES >
ENCRYPTION > ON (Manual) > KEEP KEYS.
2.
Press ENTER.
3.
Perform an IR Sync to share the encryption key with the first transmitter.
4.
Turn off the transmitter and perform an IR Sync to
share the key additional transmitters.
Caution! Make sure only one transmitter is turned on during an IR sync or a perfor-
mance to avoid causing cross interference between transmitters.
Regenerating Encryption Keys
Periodically regenerating the encryption key maintains security for transmitters and receiv-
ers that are paired for extended periods.
1.
From the receiver menu: DEVICE UTILITIES > ENCRYPTION
> ON (Manual) > REGENERATE KEYS.
2.
Press ENTER.
3.
Perform an IR Sync to share the encryption key with the first transmitter.
4.
Turn off the transmitter and perform an IR Sync to
share the key additional transmitters.
Caution! Make sure only one transmitter is turned on during an IR sync or a perfor-
mance to avoid causing cross interference between transmitters.
Removing Encryption
1.
From the receiver menu: DEVICE UTILITIES ENCRYPTION OFF
2.
Press ENTER.
3.
IR Sync the transmitter and receiver to clear the encryption key.
Note: If multiple transmitters are encrypted to a single receiver, each transmitter must be
IR synced to clear the encryption key.
