SETTING UP DATE AND TIME:
As your viewer has capability to take images and record video, time and date
is automatically stamped onto each image and video recording. To set the
correct date and time, please follow this procedure:
Turn the unit ON. After image appears, press IR Button (13) and hold it for 2
seconds. Menu will appear on the image screen. Default date format is
MM/DD/YYYY. To adjust the numbers, press Image Button (11) either in + or
– direction. To switch between date/month/year, press Power button (12).
After Date is set, adjust the time. Time is in 24hr format, so 13:00 is 1pm;
17:30 is 5:30pm and so on. As with the date, changing hours and minutes is
done with Image button (11) either + or – and moving between hours and
minutes is done via Power button (12). Once the time is adjusted you may
choose to change the date format from the factory setting MM/DD/YYYY to
DD/MM/YYYY or YYYY/MM/DD according to your preference. Once you are
finished setting date and time, you must confirm your setting by pressing PIC
button (10).
FOCUSING THE UNIT:
To obtain the sharp image, you must first rotate the objective lens (1) in
either direction, until you notice in which position the image is at its best.
After that, rotate the ocular (2) also until the image is at its best. You may
have to repeat the process again, until the image is sharp and clear. Once
the clear image is obtained, you no longer need to adjust the ocular, just
rotate the front objective lens to adjust the distance to the object you are
viewing.
BRIGHTNESS ADJUSTMENT:
Your digital viewer is equipped with dual brightness control. An automatic
brightness control sensor adjusts the image brightness according to the
available ambient light. In addition a smooth brightness adjustment wheel
(14) allows you to fine-tune the image brightness depending on the ambient
light conditions. Please note that during daylight you will need to tone the
brightness down to avoid image flickering and to preserve the battery life.
During nighttime you could increase the brightness all the way up, however
when utilizing built-in or external IR illuminator, you may need to tone the
brightness down a bit.
ELECTRONIC IMAGE MAGNIFICATION ZOOM:
Your unit is also equipped with electronic zoom function, which allows you to
change image magnification from 5x to 20x. Please note the electronic zoom
function is different from the “digital zoom”, found on many other digital
