Compatible battery, operational limitation on flashing/Focus Light
Thank you for purchasing INON D-2000 Type3.
Please use your D-2000 within following operational limitations to avoid possible heat generation/degradation of
light emitting part and inner electrical circuit etc.
Compatible battery
Five battery types can be used with this product, as below. Make sure to use fresh 4 x AAsize batteries of
same model/manufacture.
When using Ni-MH rechargeable batteries, use Sanyo “eneloop”(HR-3UTG) only. Other Ni-MH battery
has tendency of heavy self-discharge characteristic causing sudden performance degradation, and using
other Ni-MH battery may damage strobe’s inner electronic circuit due to excessive heat produced during
charging / discharging. Sanyo “eneloop”(HR-3UTG) has cleared away these disadvantages producing
less heat operating strobe safely within operational limitations described hereafter.
【Rechargeable battery】
・ AA “eneloop” battery [HR-3UTG]
・ AA NiCad battery (1.2V)
【Non-rechargeable battery】
・ AAAlkaline battery (1.5V)
・ AA Lithium battery (1.5V)
・ AA Oxyride battery (1.5V) (*1)
*1 Operational limitation of Focus Light applied when using fresh Oxyride battery. Please refer
to next section for detail.
Limitation of Focus Light continuous mode
The Focus Light should NOT continuously turn ON more than 60 minutes and make sure to cool down its
LED unit and inner electrical circuit by turning OFF the Focus Light at least 5 minutes (0℃～25℃/32 ～
77 ) or 10 minutes (25℃～35℃/77 ～95 ).
The Focus Light should NOT continuously turn ON more than 10 minutes when using fresh Oxyride
batteries due to higher initial voltage producing excessive heat.
This limitation of Focus Light continuous mode will be 60 minutes after making more than 30 normal
(-1.5EV or less) flashes or 10 (FULL～-1EV) flashes.
For maximum battery life, the Focus Light should be turned ON only when necessary to minimize heat
generation and battery drain.

Limitation on repeated flashes
The table below explains maximum number of repeated flashes (*2). Make sure to cool down light
emitting part and inner electrical circuit of the strobe by NOT making flash for at least about 2 minutes (0℃
～25℃/32～77)or at least about 4 minutes (25℃～35℃/77～95).
Also additional 10 minutes cooling-down period is required by turning OFF the Main Mode Switch after
total number of flashes according to the table below.
Also take extra cooling-down period to maintain initial performance of the product according to frequency
of usage and generated heat.
