INTRODUCTION
The HO-1410 is acompact Elaetronk; Key«r vnth abuilt-in AC power supply,
mechanical paddles, sidetone oscillator, and speaker In one package. It is
designed and styled to complefnent the "SB" Series, and is compatible with
virtually sH modern trummltten md truwalven, as well us moix oUar
The following faeturviinirite the EkMtronie Keyer versatile:
•"lamUc" operation -Leu you fonm many Morse code characters
with lass wrist movement ^an is required with keyers that tack this
feature. If the two independent peddles are treated as one, operation
is identical to singte-paddie keyers with dot and dash memories. Dots
and dashes are self-completing, and proper ratio Is always
maintained.
•Built-in sidetont osdllator and speaker with adtuctebie tone and
volume.
•Headphone iack on the rear panel that silences the speaker. Recaivsr
audio fed to the headphones by aseparate rear panel jack.
•Solid-state output eliminates the bounce and sticking problems
associated with relays.
•Weighted cabinet to prevent the keyer from stiding on the (grating
surface.
0Rear panel jacks are provided for an external key, and for operation
from an extemat battery (polarity protected) for portable operation.
The line cord dtscofmaots from Electronic Keyer for battery
operation.
•Front penel "HoM" switch allow* transmitter tune>up.
Low profile styling and small size permit the Electronic Keyer to be set in front
of most ham rigs and not block controls or take up valuable space. The
versatility and reliability of this K»yer vM make It awetoome addition to your
ham f^rtlon for years to coma.
Built-in paddles have excellent "feel" and are easily adjustable for
tension and travel.
Refer to the "Kit BuUdera Quide" tor Information on parts Identification,
toola, wiring, and 9olttertng.

CIRCUIT BOARD ASSEMBLY
Due to the small foil area around circuit board holes at integrated circuit
sockets, and the small areas between foils, use the utmost care to prevem soklL'r
bridges between these adjacent foil areas. Use only aminimum amount of solder,
imd do not heat components excesstvety with the soldering iron. Diodes,
transistors, etc., can be damaged if subjected to excessive amounts of imkt„
Apply the soldering iron only long enough to make agood solder connection. *'
NOTE :When you solder integrated circuit sockets you will need asmall wattage,
small-tip sotdertng iron. If one of these is not available, piui:t.'i'il ,is follows: Be
sure your soldering iron is cool. Then wrap the large bare wtru. bupfilied with this
kit, tightly around the soldering iron tip as shown in Figure 1.Allow
approximately 1/4" Qf ^rife .j;a;aKtjiO0 i>^onc| the end oUh^ soldering iron. Cut
