LONG RANGER IV: OPERATING INSTRUCTIONS & TROUBLESHOOTING GUIDE

CONTROLS AND FUNCTIONS: FRONT PANEL
12V DC EXT POWER
A special jack used to connect an external 12 Volt DC source to the unit to substitute for the “on-board” battery pack. It is most commonly used for
connecting the Long Ranger to a vehicle cigarette lighter or 12V DC auxillary receptacle. When an external power source is connected to this jack,
the on-board battery pack is automatically disconnected. Connectors and power supply cables are available from electronics parts suppliers such
as Radio Shack.
EXTERNAL 8 OHM SPEAKERS
Two jacks which are used to connect external 8 ohm loudspeakers such as the Lectrsonics H300 re-entrant horn. This jack can also be used to power
other brands of loudspeakers, but be sure that the speaker has a rated impedance of 8 ohms. The left-hand jack disconnects the built-in horn when
the plug is inserted. The right-hand jack will operate the internal horn along with the external speaker. The effi ciency of different makes and models
of speakers varies signifi cantly. Even though two different speakers are both rated at 8 ohms, their loudness could be quite a bit different. The other
specifi cation to compare when considering the use of another speaker is the effi ciency rating. The horn built into the Long Ranger is rated at 107 dB
SPL (sound pressure level) at one meter with a one watt input. Check this specifi cation on the speaker you are considering. A speaker with a lower
“dB’ number will not be as loud as the horn built into the Long Ranger.
