1) Allow you to manually move the antenna up/down in two speeds. When corresponding UP/DN button is
pressed and held, antenna will move slowly, and if the button is held down more than four seconds, it will
move rapidly. This will allow you to make small adjustments during fine tuning of the antenna. Each time
up/down is released, it resets the speed to slow, which allows you to ‘bump’ the motor in either direction,
allowing an exact tune.
2) Enable the variable (internal) adjustment pot to increase the medium and slow motor speeds(for
Scorpion and HI-Q), and sets the ‘soft’ limits, so that movement of the antenna will not reach the motor
current limit points. When either upper or lower limit is reached, TuneMatic will spell out ‘H L’ (higher limit),
TuneMatic will spell out ‘L L’ (lower limit), and stop further movement, preventing the antenna from traveling
beyond these soft limits.
3) ‘Park’ antenna, by pressing both UP and DOWN arrow buttons at same time. This is useful when
antenna height needs to be lowered to its minimum position during specific driving conditions. Parking the
antenna also re-calibrates the pulsecount to the initialized settings. Note that you can only park the antenna
AFTER initialization, NOT in autotune mode, and NOT if you is moving the antenna up or down (antenna must
be STOPPED to park it). The park position is at the lower soft limit point, which assures bottom of travel, and
proper re-set of pulsecount calibration. Note that parking the antenna also re-calibrates the pulse count.
4) Manually store frequency presets (see section 5).
5) Automatically operate the TuneMatic (see section 6).
6) Re-Initialize TuneMatic if necessary. NOTE: RE-initializing antenna will not disturb memory settings
(see section 3).
7) Sense lack of pulses within several seconds after start of any motor movement, If the missing pulse
detector trips, it will stop the motor, and spell out “P E” in Morse code tone. It will automatically de-initialize the
TuneMatic (without losing memories), and require you to re-initialize.
IF MOTOR DOES NOT MOVE DURING INITIALIZATION, AND YOU RECEIVE A PULSE ERROR (PE)
MESSAGE, CHECK THE WIRING BETWEEN TuneMatic AND ANTENNA.
C-2 RE-INITIALIZATION:
The TuneMatic depends on precise feedback information from the antenna. If the pulse counting sequence is
interrupted for any reason the TuneMatic may need to be re-initialized. As the antenna is used and antenna
characteristics may change or other physical changes occur, it may cause errors. This condition will
necessitate a re-initialization. If it becomes necessary to re-initialize the unit, stored memories will be retained
unless a full factory reset is performed.
TuneMatic also reverts back to an un-initialized state during some failure conditions, such as:
1) Missed pulses during antenna movement after initialization- This can happen if the connection between
the antenna pulse switch (internal to the antenna) either fails, or the wiring becomes disconnected.
2) Motor fails during antenna movement, or antenna current DIP switches are set incorrectly
3) Antenna current limit is reached (when NOT in park mode)- This can happen if there is a catastrophic
failure in the TuneMatic software, major pulse count error, or other software failure.
4) Power to TuneMatic is interrupted during antenna movement – If the TuneMatic power is disconnected
while the antenna is moving, it will cause the pulse count to lose track of where it was last. TuneMatic detects
this loss of power, and automatically puts TuneMatic into the uninitialized state. This process assures you that
the antenna pulse count integrity is maintained through all operations.
You will know the initialized state of TuneMatic upon power up. If you don’t hear the “I I” Morse
message on power up immediately after the ‘OK’ message, TuneMatic is NOT initialized.
It would also be necessary to re-initialize if you disassemble the antenna for servicing. ‘De-initialization’ only
occurs after antenna has been initialized the first time, and any occurrence of antenna/pulse error.
To perform re-initialization if already initialized:
