The user has access to the following components:
1.1 THE ANTENNA.
The RF signal is radiated by a quarter-wave reduced height helical antenna
which screws onto the top end of the transmitter box. The transmitter should
never be operated without this antenna in place, as damage to the RF
components could result. Such operation will void the warranty.
Antennas with green rings are used for 315 MHz, with blue rings for 418 MHz,
and with red rings for 433 MHz. Be sure to use an antenna that matches the
transmitter frequency, or range will be seriously degraded. Be careful not to
overtighten the antenna when screwing it on, as this could put excessive stress
on the internal connections to the mating connector. The recommended way to
install the antenna is to grasp it by its small diameter upper part and rotate gently
in a clockwise direction until increased resistance is felt. It need not be very tight
to achieve a good electrical connection. The antenna can be removed for
storage.
1.2 THE PWR / RST BUTTON.
This is a dual function button. It can turn the transmitter power on and off, or it
can initiate the transmitter’s reset / channel-change function, depending on how
and when it is pressed.
If the transmitter is off, pressing this button instantly turns power on, with the
transmitter initialized to cue 1 on its base channel. If the transmitter is on,
pressing and holding this button for at least 0.75 second turns power off.
The transmitter turns off its power automatically after 90 minutes of inactivity in
order to prevent accidental depletion of its batteries while in storage.
Pressing the Pwr / Rst button for less then 0.5 second while the transmitter is on
places the transmitter in channel-change mode, as indicated by a continuously
illuminated cue indicator. The transmitter will switch to the channel number
selected by the next numerical button press, and the cue number for that
channel will be reset to 1. If more than 4 seconds elapses without a button press
after channel-change mode is entered, the transmitter will revert to its previous
flashing mode without affecting channel or cue number. If the Pwr / Rst button is
pressed instead of a numeric button within the 4 second timeout period, channel-
change mode is canceled, and a RESET command is transmitted to all receivers
set to the transmitter’s digital channel. Operation of the transmitter is also reset
to cue 1 This feature is useful for restarting automatic-fire sequences from cue 1.
It does not affect the function of the numeric keys or the ARM state of the
transmitter.
