Manual Switch
SPST-NO Output
A 3-position selector switch, located at the lower left corner of the
front panel, determines output operation. In the OFF position, the
control output is forcibly turned OFF regardless of the setting of the
programming tabs. Set to the AUTO position, the output is turned ON
and OFF according to the settings of the programing tabs. In the ON
position, the output is forcibly turned ON regardless of the setting of
the programming tabs.
SPDT Output
When the manual switch at the lower left corner of the front is set to
the OFF position, both load 1 (connected across terminals 4 and 5)
and load 2 (across 5 and 6) are turned OFF.
When it is set to the AUTO position, the output is turned ON and OFF
according to the setting of the programming tabs.
When the manual switch is set to the ON position, load 1 (connected
across terminals 4 and 5) is turned ON and load 2 (across 5 and 6) is
turned OFF.
Output Indicator
The output indicator at the upper left corner of the front panel shows
the status of the output when the manual switch is set to the AUTO
position.
In addition, the output can be manually turned ON or OFF by rotating
the knob clockwise (in the arrow direction). The knob will not turn
counterclockwise.
Precaution for the H2F-D, -DF Series (Synchronous Motor
Models)
Before using the H2F, select the appropriate frequency of your area

Battery
Remove the battery cover on the rear panel of the H2F, load the pro-
vided Battery into the battery box, then turn ON the H2F. Be sure to
load the Battery before using the H2F. If the Battery is not loaded, the
H2F will not work properly.
Be sure to load the Battery with the correct polarity. The polarity is
indicated in the battery box. After loading the Battery, be sure to
place the cover on the battery box.
The Battery is fully charged before shipment. The Battery may lose
its charge while the Battery is stored. Therefore, there is a backup
function that is guaranteed for 180 hours on condition that the Bat-
tery is loaded into the H2F and charged continuously for 72 hours. If
the Battery has no charge, the H2F may not operate immediately
after it is turned ON. In that case, continue providing power to the
H2F for three or more minutes before setting the time.
If the H2F is turned ON and OFF frequently, the Battery life will be
greatly reduced. Use the H2F with a continuous supply of power.
The Battery has a life of approximately three years at room tempera-
ture. If three years have passed since the Battery was loaded,
replace the Battery as soon as possible with a AAAA-size NiCd
rechargeable battery.
If the H2F is idle over a long time, unload the Battery from the H2F
and store the Battery separately in order to prevent the Battery from
being overly discharged.
Always turn OFF the power supply before replacing the Battery.
Use only the specified Replacement Battery (Y92S-42). Using any
other battery may result in leakage of battery fluid or battery rupture,
possibly causing equipment damage or injury.
Other Precautions
When connecting to a heater, always use a thermal switch in the load
circuit.
Do not exceed the specified ranges for vibration and shock.
The H2F is neither waterproof nor oil-proof. Do not use the H2F
where it would be subjected to water or oil.
