2. Product description

2.1. Introduction

This professional CATV/TV Level Meter has been designed for the
installation and maintenance of Cable TV and VHF/UHF TV system.
The inside circuitry and mechanical design has been carefully
developed in order to obtain very light, slim typed field strength meter.
To allow the installer to work in the best conditions, it is also offering
built-in power (rechargeable battery) and hang-on-the neck type
carrying case. The LCD display with Back-light is shown several kinds
of information such as Frequency, Measuring level, Function, units
and bar graph. The compact metal cabinet will be a right choice for
heavy-duty field use. It is a real instrument to measure, verify and
optimize Cable TV and VHF/UHF TV systems at any stage of
installation.

4. Installation

4.1. Initial Inspection

This instrument was carefully inspected both mechanically and
electrically before shipment. It should be physically free of damage. To
confirm this, the instrument should be inspected for physical damage
in transit. Also, check for supplied accessories.

4.2. Charging and Discharging Instruction

a. New batteries are supplied in an uncharged state. To ensure the
maximum battery performance, a new battery (or long time not­ used-battery) should be charged for at least 10 hours before use.
b. A new battery will require several full-charge/discharge cycles in
order to achieve its optimum performance. After 1

st

full charge,
use battery until full discharge level, and 2nd charge to full level,
Repeat this cycle several times before starting the main use of
battery.

-21-

c. Best battery performance will be achieved when you regularly
charge and discharge batteries.
d. If left unused, a fully charged battery will discharge itself in
approximately one month.

** Please refer to “7.2 Battery Charging, page 4-1“ for the details
of charging method.
