sync.
Send Frequency
Sends operating frequency to the transmitter, each chan-
nel separately. Press the UP button to send the Channel
1 frequency, and the DOWN button to send the Chan-
nel 2 frequency. Success for digital compat modes is
indicated on the receiver as "IR Sync OK." For digital
modes, failure will be indicated on the receiver as "IR
SYNC FAILED." For Hybrid compat modes, success will
be indicated on the transmitter as "IR SYNC." Failure
will be indicated on the transmitter as "CP Err" or "Block
Mismatch" depending on the transmitter model and the
source of the error.
Send All
(available only for digital compat modes)
Sends frequency, channel name/s, and Talkback state to
the transmitter. Press the UP button to send the informa-
tion from Channel 1, and the DOWN button to send the
information from Channel 2. Since two-way IR Sync is
only available for digital transmitters, "N/A" will be next
to any channels that are in a Hybrid compatibility mode.
Get Frequency
(available only for digital compat modes)
Send or retrieve (get) frequency from the transmitter.
Choose encryption type by pressing the UP and DOWN
buttons. Select MENU/SEL to get frequency.
Get All
(available only for digital compat modes)
Retrieve (get) transmitter's frequency, Talkback state, and
channel name. Press the UP button to get all and use for
Channel 1. Press the DOWN button to get all and use for
Channel 2. Since two-way IR Sync is only available for
digital transmitters, "N/A" will be next to any channels
that are in a Hybrid compatibility mode.
Group Sync
These functions allows you to send or get Tuning groups
via IR sync to/from transmitters and receivers capable
of using Groups (DSR , DCHR, DBSM, DBSMD, DPR,
DPR-A). Use MENU/SEL button to navigate between
the group choice and the send/get mode. With the group
letter(s) highlighted, use the UP or DOWN buttons to
select which frequency group (or all groups) to send or
get. Then press the MENU/SEL button to select Send
or Get. Use the UP or DOWN buttons to toggle between
Send or Get. Then, press MENU/SEL again and "Go" will
appear in the lower right corner. Press the DOWN button
to complete the sync operation.

Encryption Key Management

The DSR has four options for encryption keys:
• Universal: This is the most convenient and basic
12
option available, and the default setting on all Lec-
trosonics D2 digital units. All encryption-capable
Lectrosonics transmitters and receivers contain
the Universal key. The key does not have to be
generated in the DSR. Simply set the Lectrosonics
encryption-capable transmitters and receivers to
Universal key type, and the encryption is in place.
This allows for convenient encryption amongst
multiple transmitters and receivers, but is not as
secure as creating a unique key.
• Shared: This key policy is designed for sports cov-
erage and similar applications where a unique key
provides enhanced security, but multiple transmit-
ters and receivers can share the same key. Once
generated by the receiver, the key can be trans-
ferred via IR to transmitters or additional receivers.
• Standard: This key policy provides excellent se-
curity, second only to the Volatile key policy. Once
a unique key is created in the receiver, it can be
transferred via IR only to transmitters, but not to
other receivers. The receiver tracks the number of
times the key is transferred. Once a Standard key
has been transferred 256 times, an alert will indi-
cate that a new key must be created.
• Volatile This is the most robust key policy avail-
able. After a unique key is created, it can be
transferred only to transmitters, not other receivers.
If a transmitter is powered off, it must have the key
sent to it again from the receiver. If the receiver is
powered off, a new key must be generated and
sent to the transmitters. In encryption terms, this is
the "one time use" key management policy.
Encryption Keys
The DSR generates high entropy encryption keys to sync
with encryption-capable transmitters. The user must
select a key type and create a key in the DSR, and then
sync the key with the transmitter.
1. Begin by selecting a Key Type.
IR&Keys --> Key Type --> Universal, Shared, Stan-
dard or Volatile.
2. Next, if using the Shared, Standard or Volatile key
type, select MAKE KEY to generate a new key.
Select "Yes" to confirm Make Key. IR&Keys -->
Make Key.
NOTE: When Universal Key type is selected,
there is no prompt to create key, as it is not
necessary.
3. A message will indicate that an Encryption Key has
been created.
4. Sync new key with transmitter (see Send Key). The
transmitted audio will then be encrypted with the
new key.
Send Key
Select SEND KEY to transfer the encryption key to
any compatible transmitters or, in Shared key policy,
additional receivers. Success will be indicated by the
LECTROSONICS, INC.
