Manley Remora Remote Control - Manual (Page 3)

The tuned antenna is positioned at the top or “nose” of the transmitter housing. Best range can be obtained by
keeping your hand clear of the top of the enclosure during operation. Range may be severely cut if the remote is
placed on a conductive (metal) surface, such as a filing cabinet or other piece of equipment, since the metal
plane will grossly detune the antenna. When the transmitter is operated in the palm of your hand, you may
expect the remote range to be at least 15 meters line-of-sight, typically 20 meters (or more) in most settings.
Radio-based systems can be affected by noise or interference occurring on the operating channel. Various
government bureaucracies dictate what radio channels may be used depending on several factors such as country
where the remote system is to be operated, the exact nature of the transmitted information and so forth. Because
of these limitations, the channels used for remote controls of this sort can be crowded, especially where
population density is high. In addition to on-channel interference, the desired radio signal may be received
perfectly when the remote transmitter is in one location, but mysteriously “drop out” when the transmitter is
move a few inches one way or another. The transmitter may need to be rotated or relocated slightly to avoid RF
“null” points.
The Remora system is highly resistant to false operation due to noise or other remote signals, but the range will
be reduced if the competing signals or noise is very strong. If you experience intermittently poor range, briefly
try operating the equipment at another location free of possible sources of interference before contacting your
dealer or Manley Labs.
Keep the remote and all other parts of the system away from rain or moisture of any sort. The Remora Remote’s
circuitry is extremely intolerant of moisture intrusion. In the event the remote transmitter gets wet, remove the
battery immediately, disassemble the case and try to remove as much moisture as possible as soon as you can.
Then let the assembly air-dry in a warm place for a day before re-assembling and testing. DO NOT disturb any
trimpot settings or move the antenna components.
Remove the battery promptly when it becomes weak or discharged or if the remote transmitter is not going to be
used for a protracted period of time. This will help prevent corrosion due to battery leakage.
The motorized volume attenuator may safely be actuated by hand, or by the motor under remote command. The
attenuator has a slip-clutch transmission, so it is safe to occasionally over-ride the motorized action by hand, or
let the clutch slip after the attenuator reaches its end stop. However, the motorized attenuator assembly will last
longer if these actions are avoided.
How to establish the digital link (pairing) between the Remora transmitter and the receiver:
Each transmitter and receiver-decoder set is designed to respond to a specific data string as programmed into the
transmitter and later acknowledged by the receiver-decoder. A small set of user-defined user-numbers is used as
part of the data string so that the remote system can be programmed to avoid unwanted operation of another
Remora-enabled Manley preamplifier that may be nearby, in range of the transmitter.
If necessary, you may alter the specific short user-number of the transmitter. When you do so, the receiver can
easily be reprogrammed to follow the changes and react to the new user-number. Having unique handshake ID
codes is important for RF remotes since unlike infrared systems, the remote’s RF commands can penetrate walls,
floors, and doors, which might operate other Manley Remora-enabled gear if they all had the same user-
numbers!
The user-numbers are a pair of single-digit numbers created by hitting the up and down buttons during a remote
transmitter programming session. How to program the user-numbers is one of those procedures that is harder to
write down than to actually do physically.
To get acquainted with the remote transmitter itself, we’ll start with a simple matter of determining the Remora
Remote’s user-number setting without changing the user-number. This requires only one action by you, the user.
You’ll get to see some of the Remora Remote’s “modes” as indicated by the LED lamp.
