g. Adjustment of Bypass Gain
Notes
Place the NORMAL/BYPASS switch in the BYPASS position.
Adjust the bypass gain control on the Cat. No. 249 Power Supply card for a SPL 3 dB less than you noted in the NORMAL mode at Step 4. If this level cannot be achieved via the control, disconnect the CP65 from AC power, remove the Cat. No. 249 card, switch the J1 jumper from the Low to the Hi position, reinstall the Cat. No. 249 card, reconnect AC power to the CP65, and readjust the SPL to the required level.
