AMERITEC AM-48 - Quiet Send Mode; Figure 5-3. Quiet Send Mode Self Test

Self-Test Instructions (18-0015) AM-48 Test Set
0015-S055-4
The FILTER menu cursor (controlled by Switch 4) will default to
C-MSG (PSHO
for AM-48E) when power is turned on. Leave the
cursor in this position for all the tests in this section.
5.3 Quiet Send Mode
Quiet Send Mode switch settings and display are depicted in Figure
5-3.
A. Verify that the SEND menu cursor is in QUIET (default position
when power is first turned on). Rock Switch 6 if necessary to
move cursor to QUIET.
B. Verify that the MEASURE menu cursor is in L/F (default position
when power is first turned on). Rock Switch 5 if necessary to
move cursor to L/F (level/frequency).
C. Display should read “UNDR” with units “DBM” and “HZ”.
D. Rock Switch 5 to move cursor to NOISE (to the right of L/F
).
E. Display should read “UNDR” with units of “DBRN” (“DBM” for
AM-48E).
