The moulded IEC connector of the supplied mains lead should be plugged into the socket (11) on the rear of the unit first and then plugged into the mains supply. The Mains power switch (14) is on the rear panel of the preamplifier. This switch is normally left on. If the unit is likely to be unattended for a long period, switch it off and unplug the mains lead from the wall.
USING THE CONTROLS MODE CONTROL The MODE button has the following functions: • It activates the preamplifier from Standby. • Pressing the MODE button once with the preamplifier activated will mute the volume level by 20dB. The MODE indicator light will glow ORANGE. The amplifier remains fully functional in this mode. Another single press unmutes the preamplifier and the MODE indicator light will revert to RED.
REMOTE HANDSET The Caspian System Remote Handset uses two AAA size 1.5V batteries. These are housed in the battery compartment on the underside of the handset. Carefully remove the battery compartment cover and insert the supplied batteries in place observing polarity. Replace the cover. The handset is now ready for use. The front panel controls of the Caspian preamplifier are replicated on the remote handset.
