OPERATION & MAINTENANCE GUIDE XMTR1M Single Command Transmitter HOLATRON SYSTEMS, LLC 833 ILANIWAI ST, STE. 2 Honolulu, HI 96813 (808) 372-0956 www.holatron.
WARNING Holatron Systems specializes in the design and manufacture of standard and custom electronic control systems where reliability and error free data communication are critical. The transmitter described in this manual is part of a system intended to remotely actuate pyrotechnic or other hazardous devices, and the components of this system have been carefully designed to minimize the possibility of accidental actuation of such devices.
NOTE: This device complies with part 15 of the FCC Rules contained in CFR 47. It has been assigned FCC ID number: OI4XMTR1M. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
This manual is divided into two sections. The first is a description of the system hardware. The second covers the recommended operating and maintenance procedure. 1.0 HARDWARE DESCRIPTION. The model XMTR1M Single Command Transmitter is a low power hand-held remote control transmitter which transmits a single fixed encoded command with an attached channel number code and group number code while its external pushbutton is pressed. No transmission occurs while its button is not pressed.
1.2 THE “BATTERY LEVEL” INDICATOR. This red lamp, located internally, verifies that battery voltage is adequate to transmit a signal over the specified range. It is actuated while the external button is pressed and the channel number switch is set to position “0”. This lamp flashes 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.
1.7 THE GROUP NUMBER SWITCH. This switch, located on the internal circuit board with silk-screened identification, is accessed by removing a transmitter side-plate. It is a 16 position miniature rotary switch that can be rotated with a small screwdriver. Positions A through F are used to select transmitter group A through F, respectively. Position 0 is used to select group G. The remaining switch positions are not used. 1.8 RADIO INTERFERENCE REDUCTION.
1.9 SPECIFICATIONS. Parameter Carrier Frequency, MHz.
2.1.3 When the transmitter is being stored or otherwise not used, the protective top cover should be kept closed to prevent actuation from accidental button depression. 2.1.4 It is advisable to check the battery level periodically by removing the sideplate, setting the channel number switch to position 0, and holding down the FIRE button. While the button is pressed, the battery level will be displayed on the BATTERY LEVEL INDICATOR as described in section 1.2.
