User manual ICOM CM-96G

[. . . ] Place the repeater in a secure place to avoid inadvertent use by children. The heatsink will become hot when operating the repeater continuously for long periods. If a linear amplifier is connected, set the repeater's RF output power to less than the linear amplifier's maximum input level, otherwise, the linear amplifier will be damaged. Other manufacturer's microphones have different pin assignments, and connection to the repeater may damage the repeater. [. . . ] Whenachannelextensionmoduleisinstalled: While the repeater power is turned ON, push to select the desired module to operate the repeater as the base station. · The power indicator of the selected module unit lights green. o DEALER-PROGRAMMABLE KEYS Desired functions can be programmed indepen dently by your dealer. Ask your dealer for details. · Because these keys are programmable, the functions of these keys are unique to each unit. 1 PANEL DESCRIPTION 1 D Function display q w e r t ICOM q SIGNAL STRENGTH INDICATOR Indicates relative signal strength level. w LOW POWER INDICATOR Appears when low output power is selected.

DC voltage is applied to pin 1 for microphone operation. Only Icom microphones are recommended. n Rear panel connection SP-22 EXTERNAL SPEAKER ACC CONNECTOR (p. The protector is activated when the repeater temperature becomes extremely high due to the frequently access to the repeater to reduce the transmit output power level. The output power will return to the normal level when the repeater has cooled down. *1 When the [SQL Level Up/Down] key function is assigned to [SELECT]. *2 When the [CH Up]/[CH Down] key functions are assigned. Transmitting q Take the microphone off hook. e Push and hold [PTT] to transmit, then speak into the microphone at your normal voice level. IMPORTANT: To maximize the audio quality of the transmitted signal: (1) Pause briefly after pushing [PTT]. (2) Hold the microphone 1 to 2 inch (2. 5 to 5 cm) from your mouth, then speak into the microphone at a normal voice level. 7 MAINTENANCE n Troubleshooting The following chart is designed to help correct problems which are not equipment malfunctions. PROBLEM POSSIBLE CAUSE 4 If you are unable to locate the cause of a problem or solve it through the use of this chart, contact the nearest Icom Dealer or Service Center. SOLUTION · Re-connect the DC power cable correctly. 5, 6 · Check the cause, then replace the fuse with p. 8 a spare one. Power does not come · DC power cable is improperly connected. · Fuse is blown. N o s o u n d s f r o m t h e · Volume level is too low. [. . . ] The specification of the RG-213 cable gives a loss of 1. 5 dB/10 m. There will be 3 dB loss for the 20 m length used. The RF power at the antenna input will be 12. 5 watts. The dipole antenna has a forward gain of 0 dBd or 1. 6, giving an EIRP of 20 watts. [. . . ]
