The receiver IS equipped a PLL. (Phase Lock Loop) synthesized
RF module with 20(301MHz) / 30(433MHz) sets of user selectable RF channels (narrow
band FM) adjusted via simple dip-switch settings. The transmitter is equipped with
a unique removable transmitting RF board for easy replacement of transmitting RF
channels.
Lightweight and Compact
The keypad arrangement results in a transmitter that is ultra lightweight and compact
in design. Including batteries the transmitter handset is weighted at only 200g for
the 4-button models. 240g for the 6-button models. and 290g for the 10-button models.
This optimized design is almost 50% smaller and tighter than most competitive models
and much easier to carry and operate
Waterproof and Durable
The transmitter and receiver enclosure are constructed from high grade composite
materials that resist cracking and deformation commonly occurred from frequent drops
and long term exposure to heat, sunlight and harsh environments. The enclosures are
fully sealed and impervious to dust, water, oil, acids, alkaline, heat and sunlight,
which provide trouble-free operation in high moisture environments and outdoor applications
Industry's Best 2-speed Push button
Custom in-house designed 2-speed pushbuttons are extremely durable and reliable for
a minimum of one million press cycles Unlike most s-speed pushbuttons available from
other radio control manufacturers these pushbuttons are easily manipulated even when
the operator is wearing gloves. The snap action steps provides positive tactile feedback
to the operator.
Full compliance
The Alpha 500 series are designed and manufactured in accordance with FCC Part 15
Rules, European directives (CE/CB). Industry Canada Specifications (IC) and ISO[

I
The Alpha 500 series utilities advanced microprocessor control with highly evolved
system software That has redundant error checking and correcting capabilities to
ensure 100% error-free encoding. transmitting, receiving. decoding and controlling
of all output relays. This highly evolved system software includes CRC (Cyclical
Redundancy Check) and Hamming Codes (Error Recovery).
Safe and Reliable Operation
To ensure maximum operating safety the system incorporates numerous important safety
features which include transmitter pushbutton fault-detection - visual warning -
auto-shutoff, transmitter low-voltage detection - visual warning - auto shutoff,
receiver fault-detention - auto-shutoff. and receiver MAIN relay auto disconnect
then system is in sleep mode, radio interference. system run of receiving range and
when transmitter low voltage condition isdetected
Secure Operation
Both transmitter and receiver utilize advanced microprocessor control. The availability
of 32.768 sets of unique ID codes + 20 distinct RF channels ensure that only Commands
from a matching control transmitter can be carried outreducing the risk of interference
from outside Sources.
Safety MAIN Relay Circuits
For added safety the receiver system utilizes a special 'Safety relay" for the receiver
MAIN relay circuits If the receiver MAIN relay is defective (example: fails to open
or close during operation or not responding to a 'Stop' command a fault will be detected
and the System will be shut down immediately to avoid possibility of any accidents
occurring.
Power Saving Circuits
The transmitter utilizes advance power-saving circuits providing more than 150 hours
of continuous operationbetween battery replacements using just Iwo (off-the-shelf
