• Starting DIAG
Press the “POWER ” (STANDBY/ON) key of the main unit while pressing the
“FM/AM ” key and the “INPUT MODE ” key simultaneously, and DIAG will be
activated.

• Starting DIAG in the protection cancel mode
If the protection function activates and causes hindrance to trouble diagnosis,
disable the protection function as described below, and it will be possible to enter
the DIAG mode. (The protection function other than the excess current detect
function will be disabled.)

• Canceling DIAG
Turn off the power by pressing the “POWER” (STANDBY/ON) key of the main unit or the “STANDBY” key of the remote
control unit.
CAUTION: When canceling this function, check that DIAG menu No.10 PRESET (memory initialization inhibited/reserved)
has been set. [To keep the user memory, be sure to select “INHI” (initialization inhibited) from the No.10 PRESET menu
before canceling the DIAG function.]

• Display at the start of DIAG
On the FL display of the main unit, an opening message (including the version and the protection history) appears for a few
seconds followed by the diagnostic menu display of 1. ANALOG BYPAS.

seconds

(*1) If a protection function history has been recorded, the type of the protection function and the voltage value recorded last
are displayed.

If the protection function activates after DIAG has been started and the power is turned off;
When the protection function (*2) activates, the protection function history appears on the display and the power turns off.
Repair the faulty parts according to the displayed history.
(*2) When an excess current or any other faulty condition is found with the power source, DC, etc., the protection function
forces the power to turn off.

I PROTECT display
(When the power is turned on without this abnormality corrected, the protection
function activates the moment the power relay is turned on to shut off the power relay.
The display will not light.)
Cause: There is an abnormal current flow to the power amplifier.
Supplementary information: As the current of the power transistor of each channel
is detected, the abnormal channel can be identified by checking the current detect
transistor.

PS PRT display
(When the power is turned on without this abnormality corrected, the protection
function activates about 1 second later to shut off the power relay. Display may not
light if there is an abnormality with the power supply for the display.)
Cause: There is an abnormality in the power supply section (voltage).
Supplementary information: As the power from the following sources is detected, it
is possible to determine where an abnormality exists.
Main (5): Transformer secondary winding
CB222 (AC voltage)
Input (4): Regulated power supplies
±25, +12A, +12B, -12, +5D

DC PRT display
(When the power is turned on without this abnormality corrected, the protection
function activates about 3 seconds later to shut off the power relay.)
Cause: A DC output from the power amplifier of any channel is detected.
Besides the above possible causes, the cause may be a disconnected connector or around the CPU.
PS PRT and DC PRT displays include the abnormal A/D value in % (voltage value obtained by considering 5V as 100%).
Concerning this value, refer to DIAG menu No.11 AD DATA CHECK.

HTR-5450/HTR-5450RDS

• Protection history
When the protection function has activated, its history is stored in memory with a memory backup. Even when no
abnormality is noted while the unit is being serviced, an abnormality which has occurred previously can be defined as
long as the backup data has been stored. The protection history should always be cleared before returning the unit
from service.
The protection history is cleared when DIAG is cancelled by selecting "RSRV" (Memory initialization) from the setting
items of the DIAG menu No.10 PRESET or when the backup data is erased.

• Operation procedure of DIAG menu and SUB-MENU
There are 14 MENU items and some SUB-MENU items as well.

10. PRESET
This menu is used to reserve and inhibit initialization of the back-up RAM. The signals are processed using EFFECT OFF.
(The L/R signal is output using ANALOG MAIN BYPASS.)
PRESET INHIBIT (Initialization inhibited) [REMOTE CONTROL CODE: –]
RAM initialization is not executed. Select this sub-menu to protect the values set
by the user.
PRESET RESERVED (Initialization reserved) [REMOTE CONTROL CODE: 7A57 (SLEEP)]
Initialization of the back-up RAM is reserved. (Actually, initialization is executed
next time when the power is turned on.) Select this sub-menu to reset when
shipped out of the factory or to reset RAM.
CAUTION: Before setting to the PRESET RESERVED, write down the existing preset memory content of the Tuner in a
table as shown below. (This is because setting to the PRESET RESERVED will cause the user memory content
to be erased.)

11. AD DATA CHECK
This menu is used to display the A/D conversion value of the main CPU which detects panel keys of the main unit and
protection functions in % using the sub-menu. (Reference voltage 5V as 100%) During signal processing, the condition
before execution is maintained.
When in 0/1/2 page, it is not possible to operate the keys of the main unit because the values of all keys are detected. During
signal processing, the condition before execution of this menu is maintained.
DC/PS (Detection of the protection function) [REMOTE CONTROL CODE: 7A-0B
(CD SKIP-)]
DC: DC detect protection value (Normal value: 3 to 35)
PS: Power voltage protection value (Normal value: 120 to 170)
* If DC or PS is out of the normal value range, the protection function activates
to turn off the power relay.
