INSTALLATION AND OPERATION WJ-8718-19/FE HF RECEIVER
2.4.2 FRONT PANEL CONTROLS AND INDICATORS
Refer to Figure 2-2 for each of the following front panel controls and
indicators.
2.4.2.1 Push On/Off Power (Si)
Press this button in to energize the receiver. During initial installation, be
sure the line-voltage-select PC wafer on the rear panel matches the available line
voltage before energizing the receiver. Refer to paragraph 2.3.1 for the voltage
selection procedure.
2.4.2.2 Meter (Ml)
The meter contains two scales of which one is a signal strength scale with
a relative scale range of 0 to 110. This signal strength scale contains a MAN SET
mark on the scale to indicate proper signal strength in the MAN gain mode. The
other scale on the meter indicates the audio level of the LINE AUDIO output in dB
above 1 mW, referenced to 600 ohms.
2.4.2.3 Meter Switch
The LINE AUDIO and SIGNAL STR switches are utilized to select the
operational mode of the front panel meter (Ml).
2.4.2.4 Scanner Mode Switches
The Scanner Mode switches are used in various memory operations. The
EXAM switch is used to display parameters stored in memory. The AUTOSCAN switch
is used to initiate a sequential scan of memory channels. The LOCKOUT switch is
used to lock out channels from a memory scan. The THRS switch switch is used for
entering a threshold level to be subsequently compared to a received signal strength.
The DWELL switch is used during AUTO SCAN mode when a dwell time must selected.
2.4.2.5 Detection Mode Switches
These switches are used to select the desired detection mode. Available
detection modes are AM, FM, USB, LSB, CWV (variable BFO) and MA (Master/Slave).
ISB mode is not available in the WJ-8718-9/FE Receiver.
2.4.2.6 Gain Mode Switches
These switches are used to select the desired gain mode. Available gain
modes are MGC (manual), SLOW (AGC) and FAST (AGC).
