HD RADIO TEST MODE
1. How to Start/End the Test Mode
1-1. How to start the test mode
While pressing Preset 1 and Preset 3 keys at the same time,
press the reset button. Keep on pressing on the Preset keys,
until the H/U boots up. (Note : That the volume is turned up to
maximum in the test mode.)
1-2. How to end the test mode
While pressing Preset 6 key, press the reset button. If the re-
quests are made to panel removal and other modes, the test
mode is cleared.
2. Operational Specifications
Operations in the test mode are those functions needed for
tests added to the normal mode. Also, there are the following
points that are different from the normal mode in addition to
the added functions for the test mode.
• For the CRSC function, the default is OFF.
• Span switching is made ineffective and operations are al-
ways those for K-destination.
Note : When switching span in the normal mode, it is pos-
sible to receive only analog. Digital cannot be received. Also,
since the reception mode is removed from the menu,
changes cannot be made on the reception mode. This means
the unit will always function in the analog mode.
3. Operation of the Head Unit
3-1. Operation with the source ON
Only in the test mode, when Tuner/HD Radio source is ON,
the tuner condition is checked. When an error is detected, the
error content is displayed in 5 digits of frequency section. When
normal, the normal frequency is displayed.

3-2. Normal test mode
In the test mode, when Tuner/HD Radio is sourced, there are
two modes: normal test mode and reverse test mode for ser-
vicing. The differences in these modes are that allocations of
preset keys are different. Shown below are the allocations of
preset keys in the normal test mode.

3-2-1. Version display (Ez900HDS only)
In each band, pressing Preset 4 key would display versions of
the host controller and IDM. In order to display the versions,
select Title by switching DISP of H/U.
3-2-2. Reception level display (S-meter value)
In each band, by using a long-push on the Preset 4 key, dis-
play of the S-meter values begin. In the frequency section, the
S-meter value is displayed in 2 digits. For the display, select
Frequency in the DISP switching of H/U. S-meter value is up-
dated once every second. Using a long-push on the Preset 4
key would end the S-meter value display and the unit returns
to the normal frequency display.
