Drake LLC 2 Caution Statements WARNING: TO PREVENT FIRE OR ELECTRICAL SHOCK DO NOT EXPOSE TO RAIN OR MOISTURE A product and cart combination should be moved with care. Quick stops, excessive force and uneven surfaces may cause the product and cart combination to overturn. [. . . ] Carbon zinc or alkaline batteries can be used in a pinch, but NO ATTEMPT SHOULD BE MADE TO RECHARGE THEM !CHANNEL SWITCH - The channel switch selects between channel 1 (A) and channel 2 (B). If channel 1 is selected, the CHANNEL A LED on the SRR60 Receiver will light and the CHANNEL A Volume and Equalizer controls will be used. If channel 2 is selected, the SRR60 CHANNEL B controls will be active. If two microphones are used it is important that one of them be on channel 1 and the other on channel 2 so that they don't interfere with each other. CHARGE CONTACT - The battery compartment charge contact must make electrical contact with the Nickel Metal Hydride (Ni-MH) battery installed in this location so that charging can occur. It will be necessary to remove approximately 1/4 inch of insulation from the battery installed in this location. If this is not done, the batteries will not recharge when the charger is plugged in. GAIN - This control varies the level of modulation of the signal that occurs when the lavaliere wearer is speaking. Too low a setting will result in inadequate audio output from the speakers. Too high a setting can result in acoustic feedback (howl) or audio distortion. The correct setting must be determined by experimentation and may very from one instructor to another. HHM60 Microphone Controls & Connections 11 1 2 3 4 5 6 2 7 8 9 1. INFRARED TRANSMITTERS - The HHM60 has two locations for the IR transmitters. It is important to keep one of these areas uncovered when the microphone is in use so that the IR signals will reach the sensor. BATTERY CHARGING CONNECTOR - This connector is located on the bottom of the unit. The BC60 Battery Charger plugs into this connector to charge the installed Nickel Metal Hydride (Ni-MH) batteries. Do not attempt to use this charger if Nickel Cadmium (Ni-Cd) batteries are installed as the charging rate is too high for them. UNDER NO CIRCUMSTANCES SHOULD THE CHARGER BE USED IF ALKALINE OR CARBON ZINC BATTERIES ARE INSTALLED !BATTERY COMPARTMENT SLEEVE - This sleeve protects the batteries and microphone adjustments. POWER LED - This LED lights green when charged batteries are installed and the power switch is turned on. LO HI POWER SWITCH - This switch is used to adjust the power applied to the IR transmitters. Setting the switch on LO (down) will consume less battery power but will give somewhat less IR range. Setting the switch on HI (up) will extend the IR range, but will cause the batteries to discharge sooner. [. . . ] The unit must be sent to the following address: Service Department R. L.
