Installing and Using the Visor
Your VS625sd package includes a visor that was custom designed to fit snugly
around the monitor. This visor will help to shroud the monitor and improve your
viewing during sunny conditions. The visor is easily attached or removed by
using the hook and loop fasteners. It is strongly advised that you install the hook
side of the hook and loop fastener to the monitor while still at home. Make sure
the monitor is clean, warm, and dry. Peel the “hook” tape from the visor, and
then peel the tape backing off. You may now apply the sticky side of the tape
around the perimeter of your monitor. The “loop” portion of the fastener on the
visor may now be married to the hook tape on the monitor, providing shade for
those sunny days.
Battery Charging
Your Marcum system comes with a 3-stage battery charger. This style of charger
has proven to be the most effective and easiest to use of all charging systems
available. While the rate of charge is low, a completely discharged battery can
be brought back to a full charge in as little as 12 hours. Because this is a 3-stage
charger, there is no danger of overcharging your battery. When properly cared
for, a sealed lead acid battery will last for at least a couple of years. Batteries
are made to be used, and they need to be used to make the most of them. The
most important thing you can do is to promptly recharge your battery after each
use. Not charging your battery immediately after use is the number one thing
that leads to battery failure. When you get home from a trip, put your battery
on charge right away, and leave it there overnight, or for around 8-12 hours.
We often talk to people who hesitate to charge their battery after each use for
fear that the battery will develop a “memory” and this will lead to a shortened
run time—THIS IS FALSE!!! ALWAYS CHARGE YOUR BATTERY AFTER EVERY
USE!!! Be sure to use the charger that came with your system, or a similar one
that is between .5 amp and 1 amp. Using a larger charger, like you would use
on a car, truck, RV, or boat is likely to cause damage to the battery. There is
really very little danger of overcharging your battery with a low amp charger, and
most chargers automatically go into “maintenance mode” once a full charge has
been achieved.
A 3-Stage charger works like this—
Stage 1 (Bulk Stage): Constant current charging at a high voltage level at
maximum amperage to minimize charge time.
Stage 2 (Absorption Stage): Current tapers off for final 10% of charge.
Stage 3 (Maintenance Stage): Lower voltage mode to prevent electrolyte loss,
keeping your battery at full charge indefinitely.
Some common sense safety tips:
For safety reasons, it is recommended that you place your system on a flat, hard
surface like cement or tile when charging it, away from any flammable materi-
als. Be sure to disconnect the charger from the wall when not in use, and avoid
leaving your battery hooked up to the charger for extended periods of time.
