Antennas with red rings are used for 433 MHz, and antennas with blue rings are
used for 418 MHz. Be careful not to overtighten the antenna when screwing it on,
as this could cause its mating connector to rotate and break its internal
connection. Rotation could also occur, with the same result, when subsequent
removal of an overtightened antenna is attempted. 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 tight to
achieve a good electrical connection. When removing the antenna for storage,
observe the base of the mating connector to ensure that it is not rotating. If the
antenna is so tight that rotation is occurring, grasp the hex base of the mating
connector with long nose pliers, and then unscrew the antenna.

THE SAFETY LOCKING SWITCH.
The Safety Locking Switch is a miniature keylock with two positions, “Safe” and
“Xmtr Enabled”. In the “Safe” position no RF output occurs even if a button is
pressed. In the “Xmtr Enabled” position modulated RF output occurs
continuously while a button is pressed. Whether transmitting or not, a green
warning indicator near the switch flashes whenever the switch is in its “Enabled”
position and the battery voltage is above the low battery detect threshold.
Approximately 1 milliamp is drained continuously from the battery while the
transmitter is enabled and not transmitting. So this switch should always be
turned to the “Safe” position while the transmitter is not being used. Keys are
interchangeable, as all Holatron RFLS-6HSXT transmitters are keyed the same.
Firing on all receivers set to the transmitter’s digital channel always commences
at cue 1 after the transmitter has first been enabled. Thus all receivers on this
transmitter’s fixed channel can be reset to cue 1 at any time by turning this switch
momentarily to “Safe” and then back to “Transmitter Enabled”.

THE “XMTR ENABLED” INDICATOR.
This green lamp, located at the “Enabled” position of the lockswitch, warns the
user that transmission will occur when a button is pressed, and that battery drain
is occurring. It also verifies that battery voltage is adequate to transmit a signal
over the specified range.
When the transmitter is turned on (transmitter enabled) with the keylock switch,
battery status is indicated by the flashing of this lamp. It is of sufficiently high
intensity to be visible in direct sunlight and will flash intermittently in bursts of
one, two, or three flashes at a time if the battery has enough capacity to power
the transmitter. If no flashing occurs, the battery must be replaced before the
transmitter can be used reliably. Three flashes per burst indicate that the battery
has full capacity, two flashes indicate that its capacity is beginning to diminish,
and one flash indicates that it is near the end of its useful lifetime in which case it
should be replaced immediately after the current use. Adequate transmitter
output to achieve the specified range will occur as long as the battery voltage is
above approximately 7.0 volts, but the battery voltage will drop rapidly at this
point.
