cable has an aluminum braid and can’t be soldered, thus
making for a poor connection. Loss of true black in the
video picture will be noticed. Use a re-modulator device
to transmit the signal on coax cable.
Remote Control Function Details
Sonance Navigator Harbor remote control commands
can be learned into any IR keypad or learning remote.
The remote control can be used to control the Sonance
Navigator Harbor through the IR window on the front
panel or through an IR receiver connected to the
keypad connector on each zone card. All these codes
can be made into “Party” commands by using the
system setup described in figure 6.
The following is the Sonance Navigator Harbor remote
control’s commands, and a description of the
command:
ON: Turns on a single zone.
OFF: Turns off a single zone. This command is not
normally used if the K1 or K2 keypad’s external speaker
relay is being used.
ALL OFF: Turns off all six zones in the Harbor.
VOLUME UP: Increases the audio output level by one
step. (At lower volumes, the steps are 2dB and at
higher volumes the steps are 1dB.) The initial volume
setting at turn on is –40dB. Other command(s) can be
placed in the K1 or K2 keypad’s power on macro to
establish a higher or lower initial volume level at turn
on.
VOLUME DOWN: Decreases the audio output level by
one step. The initial volume setting at turn on is –40dB.
Other command(s) can be placed in the K1 or K2
keypad’s power on macro to establish a higher or lower
initial volume level at turn on.
MUTE: Mutes the zone audio output. A mute condition
is represented on the front panel by an amber LED.
When a volume command or a mute command is
issued, the mute is canceled and audio is restored.
TUNER: Selects Source 1 and activates a green LED.
DVD: Selects Source 2 and activates a green LED.
CD: Selects Source 3 and activates a green LED.
VCR: Selects Source 4 and activates a green LED.
TAPE: Selects Source 5 and activates a green LED.
TV/SAT: Selects Source 6 and activates a green LED.
Secret Commands: Secret commands are accessible in
programming software for the K1 or K2 keypad but are
not on the Navigator Harbor hand held remote control.
These commands provide improved flexibility to the
system programmer.
MUTE ON: Sets volume mute to “ON” no matter if
mute was engaged or not.
MUTE OFF: Sets volume mute to “OFF” no matter if
mute was engaged or not.
UNITY GAIN: Sets volume level to “UNITY”. Sets
volume to a tape output type level.
-22dB GAIN: Sets volume level to –22dB. This
command simulates the turn on volume level of the
original Navigator Harbor.
-28dB GAIN: Sets volume level to –28dB.
-34dB GAIN: Sets volume level to –34dB.
-52dB GAIN: Sets volume level to –52dB.
-80dB GAIN: Sets volume level to the minimum
volume setting. Use VOLUME UP commands to raise
the volume level from the minimum setting.
Zone Card Installation/Removal
Each zone card has a dedicated microprocessor so if one
zone fails, the other five should continue to function. In
the case of a zone failure, it is not necessary to return
the entire unit. Simply swap out the bad zone card and
return it to Sonance for repair.
Note: it is not necessary for all cards to be in place to
operate the unit.
If a zone card must be removed, follow these steps:
URGENT: To prevent damage to the zone card you
MUST perform Step 1 before opening the Navigator
Harbor. Sonance strongly suggests that only a qualified
technician do this procedure.
1. With the Sonance Navigator Harbor sitting on a
stable work surface, with the top cover in place and
while still plugged into a grounded AC outlet, touch
one of the top cover mounting screws with a bare
finger. This will drain the static electricity from your
body. Static electricity can easily damage the
sensitive electronics on the zone card. Once the static
is drained, you can unplug the power cord from the
AC outlet.
2. Unplug the power cord from the AC outlet.
CAUTION: To Prevent serious injury, disconnect AC
voltage before removing the top cover and do not
reconnect AC voltage until the top cover has been
replaced and secured. Sonance strongly suggests that
only qualified technicians perform this procedure.
3. Remove and save the four large Phillips screws from
the sides of the top cover. Remove and save the two
small Phillips screws from the rear of the top cover.
4. Remove the top cover.
5. Remove and save the Phillips screw holding the
small LED display board to the front sub-panel.
6. Lift the small LED board vertically about a half an
inch to free it from its lower mounting flange. It will
remain connected by ribbon cable to the switcher
card; so let it dangle next to the switcher card.
7. Remove and save the two Phillips screws holding the
RCA connector to the rear panel.
8. Gently lift the ribbon cable end of the zone card up to
disconnect the 56-pin header from the motherboard.
9. Lift the zone card and LED board vertically out of
the unit.
10.Always store and ship the zone card in an anti-static
plastic bag. These bags are usually pink in color. Static
electricity can easily damage sensitive electronics.
