User manual COBRA 148GTLE

[. . . ] This unit features advanced Phase Lock Loop (PLL) circuitry, which is used in the AM mode and in the upper and lower single sideband modes, providing complete cover age of all 40 channels shown below.

Citizens Band (CB) Radio operators are no longer required to obtain an FCC license to operate their CB equipment or provide station identification. An operator of a CB radio station is required to comply with the communications act and with the rules of CB Radio Operation. Serial No. [. . . ] If the public address feature is to be used primarily for outdoor applications, the use of a weatherproof horn type public address speaker is recommended. The durability of this type speaker plus the inherent efficiency of such a speaker will provide more than adequate results when combined with the high audio output level available from the COBRA 148GTLEE. With the PA speaker connected as outlined previously, be sure that there is physical separation between the microphone and the speaker itself. If the speaker is located too close to the microphone, acoustic feedback will result when the public address system is operated at high volume. A directional type outdoor speaker reduces the amount of isolation required. Some experimentation will determine the minimum amount of isolation required for a given sound level from the public address system. NOTE PA volume is controlled by adjusting the DYNAMIKE knob to the desired volume. When in the S-RF position, the meter swings proportionally to the strength of the received signal. When transmitting, the meter indicates relative RF output power. When in the "CAL" position, the SWR meter can be calibrated by adjusting the "SWR" control to the "CAL" mark on the meter face. When in "SWR" position, the standing wave ratio is measured. Set the VOLUME for a comfortable listening level. Set the RF gain control fully clockwise for maximum RF gain. Listen to the background noise from the speaker. Turn the SQUELCH control slowly clockwise until the noise JUST disappears (no signal should be present). The receiver will remain quiet until a signal is actually received. Do not advance the control too far, or some of the weaker signals will not be heard. Set the CHANNEL selector switch to the desired channel. Adjust the VOICE LOCK control to clarify the SSB signals or to optimize AM signals. 8. 11 Section IV Operation (Continued) OPERATING PROCEDURE TO TRANSMIT 1. Select the desired channel of transmission. Set the DYNAMIKE control fully clockwise. [. . . ] Include a typed or clearly printed name and address of where the unit is to be returned.
