THREE YEAR LIMITED WARRANTY

R.L. DRAKE COMPANY warrants to the original purchaser this product shall be free from defects in material or workmanship for three (3)
years from the date of original purchase.

During the warranty period the R.L. DRAKE COMPANY or an authorized Drake service facility will provide, free of charge, both parts and
labor necessary to correct defects in material and workmanship. At its option, R.L. DRAKE COMPANY may replace a defective unit.

To obtain such warranty service, the original purchaser must:

(1) Retain invoice or original proof of purchase to establish the start of the warranty period.

(2) Notify the R.L. DRAKE COMPANY or the nearest authorized service facility, as soon as possible after discovery of a possible defect,

of:
(a) the model and serial number,
(b) the identity of the seller and the approximate date of purchase; and
(c) A detailed description of the problem, including details on the electrical connection to associated equipment and the list of such
equipment.

(3) Deliver the product to the R.L. DRAKE COMPANY or the nearest authorized service facility, or ship the same in its original container
or equivalent, fully insured and shipping charges prepaid.

Correct maintenance, repair, and use are necessary to obtain proper performance from this product. Therefore carefully read the Instruction
Manual. This warranty does not apply to any defect that R.L. DRAKE COMPANY determines is due to:

(1) Improper maintenance or repair, including the installation of parts or accessories that do not conform to the quality and specifications
of the original parts.

(2) Misuse, abuse, neglect or improper installation.

(3) Accidental or intentional damage.

All implied warranties, if any, including warranties of merchantability and fitness for a particular purpose, terminate three (3) years from the
date of the original purchase.

The foregoing constitutes R.L. DRAKE COMPANY’S entire obligation with respect to this product, and the original purchaser shall have
no other remedy and no claim for incidental or consequential damages, losses or expenses. Some states do not allow limitations on how
long an implied warranty lasts or do not allow the exclusions or limitation of incidental or consequential damages, so the above limitation
and exclusion may not apply to you.

This warranty gives you specific legal rights and you may also have other rights which vary from state to state. This warranty shall be
construed under the laws of Ohio.

POWER SUPPLY

The MPM860AG mini processing module is a
member of the R.L. Drake 19" Mini-Rack
Series, a professional quality modular headend
system designed to optimize rack space. An
assortment of up to (12) modular units, such as
the fixed channel series of modulators, or agile
modulators, the MPM860AG, or compatible

The frequency agile MPM860AG allows front
panel pushwheel switch selection of standard
CATV channels 2 through 135, or VHF/UHF TV
channels 2 through 69. Aeronautical channels
are offset per FCC requirements. Internal
jumpers permit set up for HRC or IRC CATV

plans as well.
audio/video products can be racked alongside a
single power supply in the Drake model
RMM12, 12 position rack mount. The RMM4
rack mount accepts up to (4) modular units.

The heterodyne conversion system, in

conjunction with the use of a SAW filter,

ensures optimum vestigial selectivity for

adjacent channel headends.
The R.L. Drake MPM860AG is a miniature
analog double conversion heterodyne channel
processor designed specifically to accept a
channel 3 or channel 4 RF input from a typical
consumer CH3/4 NTSC modulator. The input
signal can be either double sideband as typical
for such a modulator, or vestigial sideband
modulated.

Note that the output of the MPM860AG is

related to the input signal's stability and level. A

nominal input level of +10 dBmV ± 3 dB is

desired at CH3 or CH4. The front panel gain

control on the MPM860AG can then be adjusted

to obtain a +45 dBmV output level. The

MPM860AG is linear and if the input level is

changed, the MPM output level will follow.
The MPM860AG contains SAW filtering to
insure that the output of the MPM860AG is a
vestigial sideband output for use in a 6 MHz
wide channel environment. Adjacent output
channels are allowed.

Lights when the unit is connected to the
required source of DC power via the rear panel
DC INPUT connector. A flashing condition
indicates an invalid channel setting or other
conditions that would cause the unit to operate
on an invalid channel. The RF output is
switched off for flashing (ERROR) conditions.

F2 - Channel Select Switch

Sets the desired operating channel for standard
CATV channels 02 through 135 or Broadcast
TV channels 02 through 69. See also Item F3
which sets the type of channel (CATV or
Broadcast TV) and sets the leading “1” for
CATV channels 100 through 135.

F3 - Mode Switch

Sets the type of channel, CATV or Broadcast TV
(“BC TV”). The first position of the switch

(“+100”) sets a leading “1” for CATV channels
100 through 135. See also Item F4 for setting
the channel. Here are two examples:
