1.2 THE SAFETY LOCKING SWITCH.
The Safety Locking Switch is a miniature cylindrical 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 red
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. The key may
be removed from the switch in either position. Keys are interchangeable, as all
Holatron RFLS-1XT transmitters are keyed the same.
1.3 THE “XMTR ENABLED” INDICATOR.
This red indicator, located at the “Enabled” position of the lockswitch, is of
sufficiently high intensity to be visible in direct sunlight. It flashes continuously
while the transmitter is enabled and the battery voltage is above the low battery
detect threshold, warning 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. If this indicator does not
flash when the lock switch is in the “Enabled” position, the battery should be
replaced. The low battery detect threshold is approximately 8.5 volts. Adequate
transmitter output to achieve the specified range will occur as long as the battery
voltage is above approximately 7.0 volts, allowing some additional operating time
after the battery voltage falls below the low battery detect threshold. While this
additional time should be adequate to complete the current sequence of
transmissions, it is not absolutely predictable, and so the battery should be
replaced at the very next opportunity.
1.4 THE FIRE BUTTONS.
These buttons are snap action dome switches under a sealed overlay, labeled
“Fire A” and “Fire B”, respectively. They have a high spring constant which
requires a firm depression for actuation, decreasing the likelihood of accidental
depression. The enabled transmitter can be kept in a shirt or jacket pocket
without fear of accidental button depression. If the receiver is set to Dual
Channel mode, a continuous output from receiver channel A occurs while “Fire
A” is pressed, and a continuous output from receiver channel B occurs while
“Fire B” is pressed. If the receiver is set to Remote Arm mode, receiver channel
A alternately latches on and off each time “Fire A (Enable B)” is pressed, and a
continuous output from receiver channel B occurs while “Fire B” is pressed and
receiver channel A is latched on. While in this mode and channel A is not latched
on, no receiver output can occur from channel B. Remote Arm mode provides
added insurance against accidental actuation of devices connected to receiver
channel B.
